LET Elementary English — Grammar and Correct UsageStudy Notes

Every word in English functions as one of eight parts of speech. The key to identifying a word's part of speech is understanding how it is used in a specific sentence, not the word alone—the same word can belong to different parts of speech depending on its function. Noun: Names a person, place, thing, or idea. Examples: teacher, Manila, honesty, classroom, DepEd, learner. Pronoun: Replaces a noun to avoid repetition. Examples: he, she, they, who, this, that, which, what. Common in formal writing and everyday speech. Verb: Expresses action or a state of being. Examples: writes, is, become, teach, learn, run. Verbs are central to sentences and drive the action or condition being described. Adjective: Modifies (describes) a noun or pronoun. Examples: diligent, three, Filipino, competent, colorful, intelligent. In classroom contexts, adjectives help describe learners and materials. Adverb: Modifies a verb, adjective, or another adverb, usually answering how, when, where, or to what extent. Examples: quickly, very, quite, carefully, yesterday, abroad. Adverbs add precision to how actions are performed. Preposition: Shows the relationship of a noun or pronoun to another word in the sentence. Examples: in, on, between, of, at, under, through, despite, regarding. Prepositions are foundational to spatial and logical relationships in sentences. Conjunction: Joins words, phrases, or clauses. Coordinating conjunctions (and, but, or, nor, for, so, yet) join equal elements; subordinating conjunctions (because, although, if, since, when) introduce dependent clauses. Essential for creating complex, coherent sentences. Interjection: Expresses strong feeling and is often set off by punctuation. Examples: Oh! Wow! Aray! Ouch! Interjections are informal but valid parts of speech, common in dialogue and expressive writing. Critical for LET success: The same word can shift parts of speech. In "She will *light* the lamp," *light* is a verb. In "the *light* rain," it is an adjective. In "Turn on the *light*," it is a noun. When analyzing a sentence for errors, always identify which part of speech each word is functioning as in that specific sentence.

Subject-verb agreement is the single most tested grammar rule on the LET. The rule is simple: the verb must agree with its subject in number (singular or plural) and person (first, second, third). The challenge lies in identifying the true subject and recognizing which subjects are singular and which are plural. **Rule 1: Intervening Phrases Do Not Change the Subject** When a prepositional phrase or other descriptive phrase comes between the subject and the verb, ignore the phrase and make the verb agree with the true subject. The subject is always the noun, not the noun in the intervening phrase. Example: "The *box* of books *is* heavy." (Subject: *box*, singular → *is*, singular verb. Ignore "of books.") Example: "The teacher, *together with her students*, *was* preparing the props." (Subject: *teacher*, singular → *was*, singular verb. The phrase "together with her students" does not change the subject number.) Key intervening expressions that never change the subject number: *together with, along with, as well as, including, in addition to, not to mention.* **Rule 2: Compound Subjects Joined by 'And'** When two or more subjects are joined by *and*, the compound subject is plural and requires a plural verb. Example: "Tom and Jerry *are* here." (Two subjects → plural verb.) Example: "The teacher and the principal *were* at the meeting." (Two subjects → plural verb.) Exception: When the two nouns together name a single thing or concept, use a singular verb. Example: "Rice and fish *is* my favorite meal." (One meal, not two separate items.) **Rule 3: Subjects Joined by 'Or / Nor / Either...Or / Neither...Nor'** When subjects are joined by *or, nor, either...or,* or *neither...nor*, the verb agrees with the **nearer subject** (the one closest to the verb). Example: "Neither the teacher nor the *students were* absent." (Nearer subject: *students*, plural → *were*.) Example: "Neither the students nor the *teacher was* absent." (Nearer subject: *teacher*, singular → *was*.) Example: "Either John or *Mary is* coming." (Nearer subject: *Mary*, singular → *is*.) **Rule 4: Indefinite Pronouns** Indefinite pronouns do not refer to a specific person or thing. Some are always singular, some are always plural, and some vary depending on their referent. Always singular: *each, either, neither, everyone, everybody, someone, anybody, nobody, one.* These require a singular verb even when they feel plural. Example: "Everyone *has* a book." (Not "have.") Example: "Each student *is* responsible for his or her learning." (Not "are.") Always plural: *both, few, many, several.* Example: "Many *are* called, but few *are* chosen." (Both plural.) Variable (singular or plural depending on referent): *some, all, none, most, more, any.* Example: "Some of the *water is* gone." (*Water* is uncountable, singular.) Example: "Some of the *books are* gone." (*Books* is plural.) Example: "All of the work *was* completed." (*Work* is singular.) Example: "All of the tasks *were* completed." (*Tasks* is plural.) **Rule 5: Collective Nouns** Collective nouns (*class, team, jury, family, committee, group, staff, faculty*) name a group of people or things. They are usually singular when the group acts as one unit and plural when the members act individually. Singular (acting as one): "The team *is* winning the championship." (One unified action.) Plural (members acting separately): "The team *are* putting on their uniforms." (Individual actions.) In Philippine schools, this is commonly tested with "class": "The class *is* taking its exam" (one action) versus "The class *are* in their different seats" (individual positioning). **Rule 6: Inverted Order and 'There / Here' Openers** When a sentence begins with *there* or *here*, the subject follows the verb. The verb must still agree with the true subject. Example: "There *are* many reasons for her absence." (Subject: *reasons*, plural → *are*.) Example: "Here *is* your book." (Subject: *book*, singular → *is*.) Example: "There *was* a teacher and three students in the room." (Compound subject with "and," but inverted order; check what comes after "was.") **Rule 7: "The Number" Versus "A Number"** *The number* is always singular; *a number* is always plural (meaning "several"). Example: "The number of absent learners *is* high." (Singular.) Example: "A number of learners *are* absent." (Plural; means "several learners.") **Rule 8: Nouns Plural in Form but Singular in Meaning** Some nouns are spelled in plural form but are treated as singular because they name single concepts: *news, mathematics, physics, economics, measles, mumps, gymnastics, athletics, civics.* Example: "The news *is* good." (Not "are.") Example: "Mathematics *is* challenging." (Not "are.") Example: "Measles *is* contagious." (Not "are.") **Rule 9: Titles, Amounts, and Units** A title of a single work, a sum of money, a period of time, or a distance takes a singular verb, because the title, amount, or unit is treated as a single item. Example: "*The Canterbury Tales* *is* required reading." (One work.) Example: "Ten years *is* a long time." (One period.) Example: "Five hundred pesos *was* donated to the school fund." (One sum.) Example: "Five kilometers *is* the distance to the market." (One measurement.) **Rule 10: Gerund and Infinitive Subjects** A gerund (verb form ending in -ing used as a noun) or an infinitive (to + base form used as a noun) is always singular, even if the object of the gerund or infinitive is plural. Example: "Reading books *broadens* the mind." (Gerund subject, singular verb.) Example: "To err *is* human." (Infinitive subject, singular verb.) Example: "Swimming and diving *are* exciting." (Two gerunds joined by "and," so plural verb.) **Rule 11: "One of the + Plural Noun + Who/That" (Relative Clause Agreement)** This rule is a classic LET difficult item. When a relative clause (beginning with *who, that, which*) modifies a plural noun in the expression "one of the + plural noun," the verb in the relative clause must be plural because it is agreeing with the plural noun. Example: "She is one of the teachers who *were* honored." (The relative verb "were" agrees with the plural noun "teachers," not with "one.") Example: "These are among the books that *have* been donated." (The relative verb "have" agrees with plural "books.") Contrast: "She is the only one of the teachers who *was* honored." (With "the only one," the relative verb is singular because "the only one" is the direct antecedent, and it is singular.) This distinction—"one of the ... who were" (plural) versus "the only one ... who was" (singular)—is tested regularly and rewards careful reading.

Tense indicates the time of an action or state of being. English has three main time divisions (present, past, future) and within each division, several aspects (simple, perfect, progressive, and perfect-progressive). Understanding when to use each tense and maintaining tense consistency within a sentence or passage is crucial for LET success and clear classroom communication. **The Twelve Tenses at a Glance** Present Simple: "I write letters." Past Simple: "I wrote letters." Future Simple: "I will write letters." Present Perfect: "I have written letters." (Action begun in the past and continuing or completed in the present.) Past Perfect: "I had written letters before you arrived." (Earlier action in a sequence of two past actions.) Future Perfect: "I will have written the letters by tomorrow." (Future action viewed as completed before a point in future time.) Present Progressive: "I am writing a letter." (Ongoing action right now.) Past Progressive: "I was writing when you called." (Ongoing action during a past moment.) Future Progressive: "I will be writing all morning." (Ongoing action during a future period.) Present Perfect Progressive: "I have been writing for two hours." (Ongoing action from past to present.) Past Perfect Progressive: "I had been writing for an hour when you arrived." (Ongoing past action interrupted by another past action.) Future Perfect Progressive: "I will have been writing for six hours by noon." (Ongoing action continuing to a future point.) **Key Tense Usage Rules the LET Tests** **Rule 1: Present Perfect Versus Past Simple** Present Perfect (*have/has + past participle*) links a past action to the present or describes an action begun in the past and continuing in the present. Use present perfect when the action is not finished or when the timing is unspecified or recent. Past Simple is used when the action is clearly finished and tied to a definite past time. Example: "She *has taught* for ten years." (She began teaching ten years ago and is still teaching.) Example: "She *taught* here from 2010 to 2015." (The period is completed and past.) Example: "I *have lost* my keys." (Just now; relevance to the present.) Example: "I *lost* my keys yesterday." (Specific past time.) In Philippine DepEd contexts: "The learners *have completed* their modules" (action just finished, relevant to now) versus "The learners *completed* their modules last Friday" (definite past time). **Rule 2: Past Perfect for Earlier of Two Past Actions** Past Perfect (*had + past participle*) marks the earlier action when two past actions are described in the same sentence. Use it for the first action; use past simple for the later action. Example: "The bell *had rung* before we *arrived*." (*Had rung* is earlier; *arrived* is later.) Example: "She *had prepared* the lesson before the learners *arrived*." (*Prepared* is first; *arrived* is second.) Example: "By the time the principal *came*, the teachers *had* already *set up* the classroom." (Setup happened before the principal's arrival.) Without past perfect, the sequence is unclear: "The bell *rang* before we *arrived*" is grammatically possible but weaker, because both are in past simple. **Rule 3: Tense Consistency (Sequence of Tenses)** Do not shift tenses without a reason. Within a sentence or a coherent paragraph, maintain the same tense unless the meaning requires a change. Unnecessary shifts confuse the reader and are a frequent LET error. Example (Error): "He *opens* the door and *sees* the guest." (Inconsistent: present and present.) Correct: "He *opened* the door and *saw* the guest." (Consistent: both past.) Example (Error): "The learners *read* the story and *are understanding* the moral." (Mixing past and present.) Correct: "The learners *read* the story and *understood* the moral." (Both past simple.) Example (Correct with reason to shift): "The teacher explains the lesson. The learners listen. Then they practice." (Narrative present, consistent.) Example (Correct with reason to shift): "I studied hard. Now I *am* confident." (Shift is justified: past effort led to present state.) In classroom narrative: "The teacher *opened* the Mathematics lesson by displaying a word problem. The Grade 4 learners *solved* it in pairs. They *checked* their answers together." (All past, consistent.) **Rule 4: Irregular Verbs** Many common verbs in English are irregular, meaning their past and past participle forms do not follow the "-ed" pattern. These are heavily tested on the LET. Mastering the following pairs is essential, especially *lie/lay/lain* versus *lay/laid/laid*, and *rise/rose/risen* versus *raise/raised/raised*. *Lie* (intransitive: to recline, to rest, to be positioned) - Base: lie - Past: lay - Past Participle: lain - -ing form: lying Example: "The learner *lies* on the mat." (Present.) Example: "Yesterday, she *lay* down for a nap." (Past.) Example: "She *has lain* there for an hour." (Present perfect.) Example: "The books *are lying* on the desk." (Progressive.) *Lay* (transitive: to place, to put down something/someone) - Base: lay - Past: laid - Past Participle: laid - -ing form: laying Example: "Please *lay* the materials on the table." (Present.) Example: "He *laid* the chalk on the board ledge." (Past.) Example: "The janitor *has laid* the mats in a row." (Present perfect.) Example: "She *is laying* the foundation for the lesson." (Progressive.) The confusion arises because the past tense of *lie* (lay) looks like the base form of *lay*. A memory aid: *Lay* always takes an object (you lay something down); *lie* does not (you just lie down). *Rise* (intransitive: to go up, to move upward) - Base: rise - Past: rose - Past Participle: risen - -ing form: rising Example: "The sun *rises* in the east." (Present.) Example: "The water level *rose* after the rain." (Past.) Example: "Steam *has risen* from the pot." (Present perfect.) *Raise* (transitive: to lift up, to increase, to bring up) - Base: raise - Past: raised - Past Participle: raised - -ing form: raising Example: "*Raise* your hand if you know the answer." (Command, present.) Example: "She *raised* her voice to be heard." (Past.) Example: "The DepEd has *raised* standards for teacher training." (Present perfect.) Example: "They are *raising* awareness about literacy." (Progressive.) Memory aid: *Raise* takes an object (you raise something); *rise* does not (it rises on its own). Other frequently tested irregular verbs: *Sit* (intransitive: to be seated) - Base: sit, Past: sat, Past Participle: sat Example: "The learners *sit* in their seats." Example: "They *sat* quietly during the exam." *Set* (transitive: to place, to establish) - Base: set, Past: set, Past Participle: set Example: "*Set* the books on the shelf." (Notice: set/set/set.) Example: "She *set* the timer for the activity." *Go* (intransitive: to move away, to travel) - Base: go, Past: went, Past Participle: gone Example: "I *go* to school every day." Example: "Yesterday, I *went* to the DepEd office." Example: "I *have gone* to that training before." *Bring* (transitive: to carry toward the speaker) - Base: bring, Past: brought, Past Participle: brought Example: "Please *bring* your materials tomorrow." Example: "She *brought* her learner's worksheet." *Come* (intransitive: to move toward the speaker) - Base: come, Past: came, Past Participle: come Example: "Come to the front, please." Example: "He *came* late this morning." Example: "The Principal has *come* to observe." **Rule 5: Present Tense for Timeless or Habitual Truth** Use the present tense to state a general truth or a habitual action, even when writing in past tense about a particular incident. Example: "The learner *knows* that water *boils* at 100 degrees Celsius." (General truth in present.) Example: "In her lesson, the teacher *explained* that the Earth *orbits* the sun." (Past narrative, but present tense for the fact.)

Pronouns are words that replace nouns to avoid repetition. A pronoun must agree with its **antecedent** (the noun it replaces) in number, gender, and person, and must use the correct **case** (subjective, objective, or possessive). Pronoun errors are among the most frequently tested items on the LET because they are subtle and easily missed by readers who do not slow down to check. **Pronoun-Antecedent Agreement in Number** A pronoun and its antecedent must agree in number: a singular antecedent requires a singular pronoun, and a plural antecedent requires a plural pronoun. Singular pronouns: *I, you, he, she, it, who (singular), this, that* Plural pronouns: *we, they, who (plural), these, those* Example: "Each student must bring *his or her* book." (Singular antecedent *each student* → singular pronoun *his or her*.) Example: "The learners brought *their* materials." (Plural antecedent *learners* → plural pronoun *their*.) Traditional rule: When an antecedent is ambiguous between masculine and feminine, use *his or her* or recast the sentence to avoid the problem. The LET adheres to this traditional standard. Using *their* with a singular antecedent ("Each student brought *their* book") is increasingly accepted in modern English but is NOT correct on the LET. Example (Traditional, required for LET): "Every teacher should submit *his or her* evaluation." (Singular indefinite pronoun.) Example (Alternative to avoid awkwardness): "Teachers should submit *their* evaluations." (Recast as plural.) Indefinite pronouns (*each, every, either, neither, one, anyone, somebody, nobody*) are always singular and require singular pronouns. Example: "Either of the boys can bring *his* book." (Singular antecedent *either*; singular pronoun *his*.) Example: "Nobody should forget *his or her* assignment." (Singular *nobody*; singular pronoun.) **Pronoun Reference (Clarity)** Every pronoun must clearly refer to one obvious antecedent. Vague or ambiguous reference is a common LET error. Ambiguous: "When Maria met Ana, *she* was nervous." (Who was nervous? Maria or Ana? The sentence is ambiguous.) Clear: "When Maria met Ana, Maria was nervous." (Recast to remove ambiguity.) Clear: "When Maria met Ana, *she* was nervous. Ana was confused." (Second sentence clarifies.) Vague reference (pronoun with no clear antecedent): Error: "The teacher explained the lesson to the learner, but *it* was unclear." (What does *it* refer to—the explanation or the lesson? Both are possible.) Correct: "The teacher explained the lesson, but the *explanation* was unclear." (Recast to use a noun.) Correct: "The teacher explained the lesson to the learner, but the learner *did not understand it*." (Clearer antecedent.) Intrusive pronoun (pronoun referring to something not actually mentioned): Error: "In the textbook, *they* discuss photosynthesis." (Who is *they*? The textbook is not a person; it cannot perform actions with *they*.) Correct: "The textbook *discusses* photosynthesis." (Use the noun as the subject.) **Pronoun Case** Pronouns have three cases: subjective, objective, and possessive. Choosing the correct case is critical for LET success. Subjective Case (used for subjects and predicate nominatives): *I, you, he, she, it, we, they, who* Objective Case (used for objects of verbs and prepositions): *me, you, him, her, it, us, them, whom* Possessive Case (showing ownership): *my, your, his, her, its, our, their, whose* **Rule 1: Pronouns as Subjects** Use the subjective case for the subject of a verb. Example: "*He* and I *are* teaching Grade 3." (Both *he* and *I* are subjects; use subjective case.) Example: "*She* *writes* the lesson plan." (Subject of the verb; use *she*, not *her*.) Incorrect: "*Him* and me are teachers." (Should be *He* and *I*.) **Rule 2: Pronouns as Objects of Verbs** Use the objective case for the direct or indirect object of a verb. Example: "The principal invited *him* and *me* to the meeting." (*Him* and *me* are direct objects.) Example: "Please give *her* the worksheet." (*Her* is the indirect object.) Incorrect: "The principal asked *he* and *I* for advice." (Should be *him* and *me*.) **Rule 3: Pronouns After Prepositions (Most Reliable Rule)** Use the objective case for the object of a preposition. This is one of the most reliably tested rules and the easiest to remember. Example: "*Between you and **me**, the lesson was challenging." (*Me* is the object of the preposition *between*; it is not the subject.) Example: "This is a secret *between* *us* and *them*." (Both *us* and *them* are objects of *between*.) Example: "The principal spoke *to* *her*." (*Her* is the object of *to*.) Incorrect: "*Between you and **I**..." (A very common error. *I* is subjective; after a preposition, use *me*.) Incorrect: "The teacher gave it *to* *he* and *I*." (Both are objects of *to*; use *him* and *me*.) A practical strategy: If a pronoun follows a preposition, it is almost certainly objective. The prepositions most frequently tested are *between, with, to, for, from, in, at, about, during, without, except.* **Rule 4: Pronouns in Comparisons with 'Than' and 'As'** When comparing with *than* or *as*, determine the correct case by mentally completing the elliptical (incomplete) clause. Example: "She is taller *than **I** [am]." (Complete the clause: "than I am." The pronoun is the subject of the implied verb *am*; use subjective *I*.) Example: "She is taller *than **me**." (This is considered nonstandard; standard is *than I*.) Example: "You speak English as well *as **we** [do]." (Complete: "as we do." The pronoun is the subject; use *we*.) Example: "He gave *more* attention *to* them *than* [to] *us*." (Elliptical: "than [he gave to] us." The pronoun is an object of the preposition *to*; use *us*, not *we*.) This rule is frequently tested because the correct answer depends on what the implied verb or preposition is. **Rule 5: Who Versus Whom** *Who* is subjective (used as a subject or after a linking verb); *whom* is objective (used as an object of a verb or preposition). Example: "*Who* called?" (*Who* is the subject of the verb *called*.) Example: "*Whom* did you call?" (*Whom* is the direct object of the verb *called*. Rearrange: "You called whom." Yes, *whom*.) Example: "*Who* is it?" (*Who* is a predicate nominative after the linking verb *is*.) Example: "*Whom* are you talking about?" (*Whom* is the object of the preposition *about*. Rearrange: "You are talking about whom." Yes, *whom*.) A reliable strategy: If you can replace the word with *he/she/they*, use *who*. If you can replace it with *him/her/them*, use *whom*. Example: "Whom did you see?" Replace: "You saw him." Yes, *whom* is correct. Example: "Who came?" Replace: "He came." Yes, *who* is correct. **Rule 6: Possessive Case and Common Confusions** Possessive pronouns (*my, your, his, her, its, our, their, whose*) show ownership and do NOT use an apostrophe. *Its* (possessive, no apostrophe): "The school celebrated *its* anniversary." (The anniversary belongs to the school.) *It's* (contraction of "it is"): "*It's* a beautiful day." (= "It is a beautiful day.") Error: "The dog wagged *it's* tail." (Incorrect; should be *its*.) Correct: "The dog wagged *its* tail." Other common pronoun confusions: *Their* (possessive pronoun): "The learners brought *their* materials." *There* (adverb of place): "The books are over *there*." *They're* (contraction of "they are"): "*They're* ready for the lesson." *Your* (possessive pronoun): "What is *your* name?" *You're* (contraction of "you are"): "*You're* doing well." *Whose* (possessive pronoun): "*Whose* book is this?" *Who's* (contraction of "who is"): "*Who's* coming to the meeting?"

Modifiers are words or phrases that describe or limit other words in a sentence. Adjectives modify nouns and pronouns; adverbs modify verbs, adjectives, and other adverbs. Modifier errors—using the wrong form, placing a modifier too far from what it describes, or leaving a modifier without a word to modify—are among the most frequently tested errors on the LET. **Adjective Versus Adverb** The choice between an adjective and an adverb depends on what the modifier describes. Use an **adjective** to describe a noun or pronoun: Example: "The *happy* learners entered the classroom." (*Happy* is an adjective; it modifies the noun *learners*.) Example: "The boy is *tall*." (*Tall* is an adjective; it describes the subject *boy* via the linking verb *is*.) Use an **adverb** to modify a verb, an adjective, or another adverb. Adverbs often end in *-ly*: Example: "She read the story *aloud*." (*Aloud* is an adverb; it modifies the verb *read*. How did she read? Aloud.) Example: "The learners spoke *loudly* in the auditorium." (*Loudly* is an adverb; it modifies the verb *spoke*.) Example: "She is *very* intelligent." (*Very* is an adverb; it modifies the adjective *intelligent*.) Example: "The teacher *carefully* explained the concept." (*Carefully* is an adverb; it modifies the verb *explained*.) **Critical Rule: Adjectives After Linking Verbs** After linking verbs (*is, am, are, was, were, be, being, been, become, seem, appear, look, feel, smell, taste, sound, remain, stay*), use an **adjective** to describe the subject, not an adverb. The adjective is called a **predicate adjective** or **subject complement** because it describes the subject. Example: "The soup tastes *good*." (Correct: *good* is an adjective describing the subject *soup*. Do not use *well* unless the meaning is "in good health.") Incorrect: "The soup tastes *goodly*." (There is no such form; *goodly* is archaic.) Example: "The learner *feels* *confident*." (Correct: *confident* is an adjective describing the subject *learner*.) Incorrect: "The learner *feels* *confidently*." (Wrong; use the adjective after a linking verb.) Example: "The music sounds *beautiful*." (Correct: adjective after *sounds*.) Incorrect: "The music sounds *beautifully*." (Wrong.) Contrast with action verbs (non-linking): Example: "She sings *well*." (Action verb; use adverb *well*.) Example: "The teacher spoke *clearly*." (Action verb; use adverb *clearly*.) A memory aid: After a linking verb, ask "What is the subject?"; the adjective describes the subject. After an action verb, ask "How is the action done?"; the adverb answers. **Well Versus Good** *Good* is an adjective; *well* is usually an adverb. However, *well* can be an adjective when it means "in good health." Example: "She is *good*." (Adjective: she is a good person.) Example: "She performs *well*." (Adverb: she performs in a good manner.) Example: "I feel *well*." (Adjective: I am in good health. This is an acceptable use of *well* as an adjective.) Example: "The learner wrote *well*." (Adverb: the learner wrote in a good manner.) **Degrees of Comparison** Adjectives and adverbs have three degrees: **positive** (base form), **comparative** (for comparing two items), and **superlative** (for comparing three or more items). Positive: good, bad, bright, quickly, carefully Comparative (two): better, worse, brighter, more quickly, more carefully Superlative (three or more): best, worst, brightest, most quickly, most carefully For most one-syllable adjectives, add *-er* (comparative) and *-est* (superlative): tall → taller → tallest; bright → brighter → brightest. For adjectives with two or more syllables, use *more* and *most*: beautiful → more beautiful → most beautiful; careful → more careful → most careful. Some adjectives are irregular: good → better → best; bad → worse → worst; little → less → least; many/much → more → most. **Rule 1: Use Comparative for Two Items, Superlative for Three or More** Using the superlative when only two things are being compared is an error. Example: "Of the two learners, Maria is the *better* reader." (Correct: comparative for two.) Incorrect: "Of the two learners, Maria is the *best* reader." (Superlative used for two; should be comparative.) Example: "Of the three learners, Maria is the *best* reader." (Correct: superlative for three or more.) Example: "The Grade 3 class is *more* organized than the Grade 2 class." (Comparative for two groups.) **Rule 2: Avoid Double Comparatives** Do not combine *-er* with *more*, or *-est* with *most*. Choose one form. Incorrect: "She is *more smarter* than he is." (Double comparative: *more* + *-er*.) Correct: "She is *smarter* than he is." (Use *-er* alone.) Correct: "She is *more intelligent* than he is." (Use *more* alone.) Incorrect: "This is the *most happiest* day of my life." (Double superlative.) Correct: "This is the *happiest* day of my life." (Use *-est* alone.) **Rule 3: Absolute Adjectives** Some adjectives are **absolute** in meaning and logically cannot be compared. These include *unique, perfect, impossible, dead, complete, eternal, infinite, certain.* An item either is or is not unique; it cannot be "more unique." Incorrect: "Her lesson was *more unique* than his." (Unique is absolute.) Correct: "Her lesson was *unique*." (Use the positive form.) Incorrect: "This is the *most perfect* circle." (Perfect is absolute.) Correct: "This is a *perfect* circle." (Use the positive form.) However, in informal speech and modern usage, some speakers use comparative forms with absolute adjectives for emphasis ("It's more perfect this way"), but this is **not** accepted on the LET. Treat absolute adjectives as non-comparable. **Misplaced Modifiers** A modifier must be placed as close as possible to the word it modifies. A modifier that is too far from what it describes is a **misplaced modifier** and creates confusion or unintended meaning. Example (Confusing): "She served sandwiches to the children *on paper plates*." (Does the modifier "on paper plates" modify "children" or "sandwiches"? The placement suggests the children are on paper plates, which is absurd.) Clear: "She served the children sandwiches *on paper plates*." or "She served *paper-plated* sandwiches to the children." Example (Confusing): "The teacher explained the lesson to the learners *with great patience* sitting in rows." (Does "with great patience" modify the teacher or the learners? The placement suggests the learners have great patience.) Clear: "The teacher, *with great patience*, explained the lesson to the learners sitting in rows." (Moved closer to "teacher.") Example (Confusing): "I saw the principal walking to the office *with a red folder*." (Is the principal or I carrying the folder?) Clear: "I, carrying a red folder, saw the principal walking to the office." or "Walking with a red folder, I saw the principal enter the office." A reliable strategy: Identify the modifier and the word it modifies, then move the modifier next to that word. **Dangling Modifiers** A **dangling modifier** is a modifier that has no logical word in the sentence to modify, or the word it should modify is not the subject of the main clause. Dangling modifiers often occur at the beginning of a sentence with a participial phrase or an introductory phrase. Example (Dangling): "*Walking to school*, the rain fell." (The participial phrase "Walking to school" has no clear subject. The rain was not walking.) Corrected: "*Walking to school*, I was caught in the rain." (Now "I" clearly walks.) Corrected: "As I walked to school, the rain fell." (Add the subject.) Example (Dangling): "*After reading the chapter*, the questions seemed easy." (The questions did not read the chapter.) Corrected: "*After reading the chapter*, the learners found the questions easy." (The learners read the chapter.) Corrected: "After the learners *read* the chapter, the questions seemed easy." (Use a full subordinate clause.) Example (Dangling): "*Sitting in the cafeteria*, the bell rang." (The bell was not sitting.) Corrected: "*Sitting in the cafeteria*, we heard the bell ring." (We were sitting.) Corrected: "While we sat in the cafeteria, the bell rang." (Full clause.) Example (Dangling): "*To succeed in teaching*, the classroom must be orderly." (The classroom does not succeed; the teacher does.) Corrected: "*To succeed in teaching*, you must keep the classroom orderly." (You succeed.) Corrected: "To succeed in teaching, a classroom must be orderly." (Only valid if the subject performing the infinitive is implied.) Dangling modifiers are a top-tier LET error-identification trap because they sound plausible to a quick reader but are logically nonsensical. When you see a sentence beginning with a participial phrase (e.g., "*Reading the story*," "*Arriving late*," "*Knowing the answer*,"), immediately check: Is the subject of the phrase the same as the subject of the main clause? If not, the modifier is dangling. To fix a dangling modifier: 1. Change the main clause so its subject matches the modifier. 2. Expand the modifier into a full subordinate clause. 3. Restructure the sentence entirely.

Prepositions are small words that show the relationship between a noun or pronoun and another word in the sentence. Prepositions are often **idiomatic**, meaning the correct choice is fixed by convention and cannot be predicted by logic alone. The LET tests whether you know and can apply the fixed preposition + word combinations that English speakers use. **Common Prepositions** Common prepositions include: *in, on, at, to, from, with, by, for, of, about, above, below, under, between, among, during, before, after, since, because of, due to, according to, contrary to.* **The Principle of Idiomatic Usage** Many prepositions cannot be substituted for one another without changing the meaning or creating an error. The correct preposition must be learned through exposure to standard English. Example: "agree *with* a person" (You agree with someone's opinion.) Example: "agree *to* a proposal" (You agree to accept a proposal.) Example: "agree *on* a plan" (You agree on a plan as a group.) These three uses are distinct and not interchangeable. Using the wrong preposition creates an error. **Frequently Tested Idiomatic Combinations** The LET regularly tests these fixed pairs or triplets: *different from* (preferred over *different than*) Example: "This method is *different from* the previous one." (Standard.) Incorrect: "This method is *different than* the previous one." (Nonstandard.) *capable of* Example: "The learner is *capable of* solving this problem." (Not *capable to* or *capable for*.) *interested in* Example: "The learners are *interested in* Science." (Not *interested on* or *interested for*.) *responsible for* Example: "Each student is *responsible for* his or her own materials." (Not *responsible of*.) *married to* Example: "She is *married to* a teacher." (Not *married with*.) *comply with* Example: "Schools must *comply with* DepEd regulations." (Not *comply to*.) *prefer ... to* Example: "I *prefer* reading *to* writing." (Not *prefer ... than*.) *distinguish from* Example: "It is important to *distinguish* fact *from* opinion." (Not *distinguish ... than*.) *consist of* Example: "The lesson *consists of* three parts." (Not *consists in*.) *depend on / upon* Example: "Success *depends on* hard work." (Both *on* and *upon* are acceptable.) *insist on* Example: "The teacher *insists on* punctuality." (Not *insists in*.) *apply for* Example: "She will *apply for* a teaching position." (Not *apply to* for a job, though *apply to* a school is different.) *apply to* Example: "These rules *apply to* all learners." (Rules apply to people.) *result in* Example: "Carelessness *results in* errors." (Not *results to*.) *result from* Example: "The accident *resulted from* negligence." (Not *resulted of*.) *similar to* Example: "Her teaching style is *similar to* mine." (Not *similar like*; *like* is not a preposition in formal English.) *based on* Example: "The lesson is *based on* the K to 12 curriculum." (Not *based at* or *based in*.) *tendency to* Example: "Students *have a tendency to* procrastinate." (Not *tendency for*.) *reason for* Example: "The *reason for* her absence was illness." (Not *reason of*.) *in accordance with* Example: "The school operates *in accordance with* DepEd policies." (A formal phrase.) *in addition to* Example: "*In addition to* teaching, she serves as a counselor." (Not *in addition of*.) *despite / in spite of* Example: "*Despite* the rain, we held the class." (*Despite* is a preposition; no *of*.) Example: "*In spite of* the rain, we held the class." (*In spite of* is a phrase.) Incorrect: "*Inspite of*..." (One word is nonstandard.) **Unnecessary Prepositions (Omission and Redundancy)** Some prepositions are required but sometimes omitted, creating errors: Example: "What are you looking *for*?" (The preposition *for* is necessary; without it, "What are you looking?" is incomplete.) Incorrect: "What are you looking?" (Missing *for* or *at*.) Example: "Where is the classroom *at*?" (Informal but accepted in speech. Formal: "Where is the classroom?" without *at*.) Other times, prepositions are added unnecessarily: Example: "I *like* reading." (Not "I *like to read*." Both are acceptable, but "I *like* reading" is preferred.) Incorrect: "I like *for* you to read." (Nonstandard; use "I like you to read.") **Ending a Sentence with a Preposition** A long-standing rule states that ending a formal sentence with a preposition is incorrect. However, modern usage and most grammar guides accept final prepositions in questions and certain contexts, especially if avoiding the preposition creates an awkward construction. Acceptable: "*What* are you talking *about*?" (Question; preposition *about* at the end is acceptable.) Formal alternative: "About *what* are you talking?" (Awkward.) Acceptable: "The lesson *we* all *benefited from*." (Relative clause; acceptable.) Formal alternative: "The lesson *from which* we all benefited." (More formal.) For the LET, treat the rule conservatively: if you can restructure the sentence to move the preposition away from the end without creating awkwardness, do so. If the sentence is already provided and ends with a preposition, it is likely not an error unless the preposition is unnecessary (e.g., "Where is it *at*?"). In formal writing and teaching contexts (aligned with RA 7836 professional standards), avoid unnecessary final prepositions: use "Where is the classroom?" rather than "Where is the classroom at?"

Two smaller but frequently tested rule sets complete the grammar coverage: articles (*a, an, the*) and correlative conjunctions (paired conjunctions that must work together). **Articles** English has three articles: *a* (indefinite), *an* (indefinite), and *the* (definite). Articles are among the most challenging aspects of English grammar for non-native speakers and are regularly tested on the LET. **Rule 1: A Versus An** Use *a* before a **consonant sound** and *an* before a **vowel sound**. The choice depends on the sound that follows, not the spelling of the word. Examples with *a* (consonant sound): - *a* book (sound: /b/.) - *a* teacher (sound: /t/.) - *a* uniform (sound: /y/, which is consonantal). - *a* one-peso coin (sound: /w/, which is consonantal). - *a* European trip (sound: /y/, which is consonantal). Examples with *an* (vowel sound): - *an* apple (sound: /æ/.) - *an* hour (sound is silent; the initial sound is a vowel: /aʊ/.) - *an* honest man (the *h* is silent; sound begins with a vowel: /ɑ/.) - *an* orange (sound: /ɔ/.) - *an* umbrella (sound: /ʌ/.) Key point: The rule is based on sound, not spelling. Despite the spelling, "a honest" is wrong because *honest* is pronounced without the initial *h* sound, so it begins with a vowel sound and requires *an*. Common LET mistakes: Incorrect: "a hour" (Spelling has "h," but the sound is a vowel.) Correct: "*an* hour." Incorrect: "an uniform" (Spelling starts with a vowel, but the sound is /y/.) Correct: "*a* uniform." Incorrect: "an European" (Spelling starts with "E," but the sound is /y/.) Correct: "*a* European trip." **Rule 2: The (Definite Article)** Use *the* for a noun that is specific or already identified: Example: "The learners in Grade 3 are studying Mathematics." (*The* specifies which learners—those in Grade 3.) Example: "She is the principal of the school." (*The* indicates a specific principal and school.) Example: "I read *the* book you recommended." (*The* specifies which book—the one you recommended.) Use *the* before nouns that are unique or one of a kind: Example: "*The* sun rises in the east." (There is only one sun.) Example: "*The* president leads the nation." (One president in a given country.) Example: "*The* teacher explained the lesson." (In context, one teacher is clear.) Use *the* with certain nouns by convention: Example: "*The* United States, *the* Philippines, *the* United Kingdom." (Geographical names with "United" or "Republic" often take *the*.) Example: "*The* morning, *the* afternoon, *the* evening." (Times of day often take *the*.) Example: "*The* piano, *the* violin, *the* guitar." (Musical instruments often take *the*.) **Rule 3: Zero Article (No Article)** Use no article with plural or uncountable nouns used in a general sense: Example: "Honesty is a virtue." (General noun; no article.) Example: "Books are valuable." (Plural in a general sense; no article.) Example: "Water is essential." (Uncountable; no article for general meaning.) Example: "Students learn best through practice." (Plural in general sense.) Use no article with proper nouns (names of specific people, places, languages, months, days, holidays), except in certain cases: Example: "Maria is a teacher." (Proper noun; no article.) Example: "Manila is the capital of the Philippines." (*Manila* has no article; *the Philippines* takes *the*.) Example: "I speak English." (Language; no article.) Example: "Christmas falls on December 25." (Holiday and month; no articles.) Use no article before possessives and demonstratives: Example: "*My* books are on the desk." (Not "the my books.") Example: "*This* lesson is about fractions." (Not "the this lesson.") **Common Article Errors the LET Tests** 1. Using *the* when none is needed: "The *Philippines* is..." (Correct: "*The* Philippines is..." because of the form of the name.) 2. Omitting *the* when it is needed: "I visited *hospital* yesterday." (Correct: "I visited *the* hospital.") 3. Using *a/an* with plural or uncountable nouns: "a water" (Uncountable; use "*water*" or "*a glass of* water"), "a students" (Plural; use "*students*" or "*a* student") 4. Confusion over sounds: "a hour" instead of "an hour." **Correlative Conjunctions** Correlative conjunctions are paired conjunctions that work together to join words, phrases, or clauses. These pairs must match and are used according to specific rules. The LET tests two aspects: whether the pair is matched correctly and whether the elements following each half of the pair are **parallel in structure**. **Common Correlative Pairs** *not only ... but also* (used to add a second idea with emphasis) Example: "She is *not only* intelligent *but also* diligent." (Two adjectives; parallel.) Example: "She *not only* teaches Math *but also* coaches basketball." (Two verb phrases; parallel.) Incorrect: "She is *not only* intelligent *but* hardworking." ("but" should be "but also"; and "intelligent" vs. "hardworking" are different structures.) *either ... or* (used to present two alternatives) Example: "The class will study *either* Science *or* Social Studies." (Two nouns; parallel.) Example: "You can *either* read the book *or* watch the video." (Two verb phrases; parallel.) Incorrect: "You can *either* read the book *or* watching the video." (Parallel error: "read" vs. "watching".) *neither ... nor* (used to exclude both options) Example: "*Neither* the teacher *nor* the principal was present." (Two nouns; parallel. Verb agrees with nearer noun.) Example: "*Neither* reading *nor* writing comes easily to him." (Two gerunds; parallel.) Incorrect: "*Neither* the boys *nor* the girls is coming." (Nearer noun is "girls" plural, so verb should be "are", not "is".) *both ... and* (used to include two items together) Example: "*Both* the teacher *and* the principal attended the meeting." (Two nouns; parallel. Verb is plural.) Example: "This lesson develops *both* critical thinking *and* creativity." (Two nouns; parallel.) Incorrect: "*Both* reading and to write are important." (Parallel error: "reading" gerund vs. "to write" infinitive.) *whether ... or* (used in conditional or alternative contexts) Example: "*Whether* you study *or* play, balance is key." (Two clauses; parallel.) Example: "I am unsure *whether* to continue *or* to stop." (Two infinitives; parallel.) Incorrect: "*Whether* you like it or not liking it, the rule applies." (Parallel error.) **Parallelism Rule** After each part of a correlative pair, the grammatical structure must be the same. If the first part is an adjective, the second must be an adjective. If the first part is an infinitive, the second must be an infinitive. If the first part is a noun, the second must be a noun. Example (Parallel): "She is *not only* *intelligent* *but also* *diligent*." (Both adjectives.) Example (Parallel): "*Neither* *singing* *nor* *dancing* was his strength." (Both gerunds.) Example (Parallel): "*Both* *to read* *and* *to write* are essential skills." (Both infinitives.) Example (Not parallel): "She is *not only* *intelligent* *but also* *works hard*." (Adjective vs. verb phrase; not parallel.) Correct: "She is *not only* *intelligent* *but also* *hardworking*." (Both adjectives.) Another test of parallelism: the words or phrases following each correlative should be of similar length and complexity. If they are very different, the sentence may be unbalanced. Example: "*Either* you study hard *or* you fail." (Parallel in structure and length.) Example: "*Either* you study hard *or* you will not receive a good grade and will feel disappointed and will regret later." (Unbalanced; second clause is much longer.) **Common Correlative Errors on the LET** 1. Mismatched pairs: "*Neither* ... *or*" (should be "*neither* ... *nor*"). 2. Faulty parallelism: "*Either* reading *or* to write" (mixing gerund and infinitive). 3. Position of conjunctions: "*Not only* he *is* intelligent *but also* hardworking" (The structure "not only ... but also" should frame parallel elements directly, not separate them with a verb).

Sentence-level errors occur when the basic structure of the sentence is flawed. These are among the most frequently tested error types on the LET, particularly in the error-identification format. Understanding these errors and how to correct them is essential for both exam success and clear classroom writing. **Sentence Fragments** A **sentence fragment** is a group of words that is punctuated as a sentence but lacks the essential components of a complete sentence: either a subject or a complete predicate (verb), or it is only a dependent clause. Requirements for a complete sentence: 1. It must have a **subject** (who or what the sentence is about). 2. It must have a **complete predicate** (a verb that expresses a complete action or state of being). 3. If it contains a dependent (subordinate) clause, the clause must be joined to an independent clause. Types of fragments: **Fragment Type 1: Missing Subject** Example (Fragment): "*Ran* quickly to the store." (Who ran? No subject.) Corrected: "She ran quickly to the store." (Subject added.) Example (Fragment): "*Was* very happy about the results." (Who was happy? No subject.) Corrected: "The learner was very happy about the results." (Subject added.) **Fragment Type 2: Missing or Incomplete Predicate** Example (Fragment): "The teacher. Very proud of her class." ("Very proud" is an adjective phrase, not a complete verb.) Corrected: "The teacher was very proud of her class." (Verb added.) Example (Fragment): "All the learners in the classroom. Ready for the exam." (No complete verb.) Corrected: "All the learners in the classroom were ready for the exam." (Verb added.) **Fragment Type 3: Dependent Clause Standing Alone** A dependent clause (introduced by a subordinating conjunction like *because, although, if, when, while, since*) cannot stand alone as a sentence. It must be attached to an independent clause. Example (Fragment): "*Because she was late.* The principal was not pleased." (The first sentence is a dependent clause; it cannot stand alone.) Corrected: "*Because she was late*, the principal was not pleased." (Joined to the independent clause.) Corrected: "She was late. *Because of this*, the principal was not pleased." (Restructured with a new independent clause.) Example (Fragment): "*Although the weather was rainy.* We held the outdoor activity." (Dependent clause standing alone.) Corrected: "*Although the weather was rainy*, we held the outdoor activity." (Joined to the independent clause.) CorrectEdited: "The weather was rainy. *However*, we held the outdoor activity." (Restructured.) **Fragment Type 4: Phrase Standing Alone** A phrase (a group of words without both a subject and a complete verb) cannot be a sentence. Example (Fragment): "*In the classroom.* The learners worked quietly." (Prepositional phrase only.) Corrected: "*In the classroom*, the learners worked quietly." (Joined to the independent clause.) Example (Fragment): "*After the lesson.* The teacher collected the worksheets." (Prepositional phrase.) Corrected: "*After the lesson*, the teacher collected the worksheets." (Joined.) Example (Fragment): "*Reading the storybook.* The learners imagined the adventure." (Participial phrase without a main verb.) Corrected: "*While reading the storybook*, the learners imagined the adventure." (Expanded and joined.) **Run-On Sentences and Comma Splices** A **run-on sentence** joins two or more independent clauses with no punctuation at all. A **comma splice** is the same error but with only a comma between the clauses (and no coordinating conjunction). Both are errors. **Run-On (No Punctuation Between Clauses)** Example (Run-on): "The learners completed their assignments the teacher checked them." (Two independent clauses with no punctuation or conjunction.) **Comma Splice (Only a Comma, No Conjunction)** Example (Comma Splice): "The learners completed their assignments, the teacher checked them." (Two independent clauses separated by only a comma; a coordinating conjunction is needed.) **How to Fix Run-Ons and Comma Splices** There are four reliable methods: **Method 1: Use a Period (Create Two Sentences)** Example (Fixed): "The learners completed their assignments. The teacher checked them." Example (Fixed): "She studied hard. She passed the exam." **Method 2: Use a Semicolon** Use a semicolon to join two closely related independent clauses. The semicolon shows that the clauses are of equal importance and related in thought. Example (Fixed): "The learners completed their assignments; the teacher checked them." (Semicolon replaces the missing punctuation.) Example (Fixed): "She studied hard; she passed the exam." Note: A semicolon is often followed by an adverbial conjunct (a word like *however, therefore, nevertheless, moreover, furthermore, consequently*) that connects the clauses logically. Example: "She studied hard; *therefore*, she passed the exam." (The semicolon precedes *therefore*, not a comma.) Incorrect: "She studied hard, *therefore* she passed." (Comma splice; a comma is insufficient.) Correct: "She studied hard; *therefore*, she passed." (Semicolon before the adverbial conjunct.) **Method 3: Use a Comma Plus a Coordinating Conjunction (FANBOYS)** The seven coordinating conjunctions are: *for, and, nor, but, or, yet, so* (memory aid: FANBOYS). A comma plus one of these conjunctions can join two independent clauses. Example (Fixed): "The learners completed their assignments, and the teacher checked them." (Comma + "and".) Example (Fixed): "She studied hard, so she passed the exam." (Comma + "so".) Example (Fixed): "The weather was rainy, but we held the activity." (Comma + "but".) Note: The comma must come before the coordinating conjunction, not after. And the conjunction must join two complete independent clauses, not just a subject and a predicate. Incorrect: "The teacher explained the lesson, and solved the practice problems." (This looks like comma + conjunction, but "solved the practice problems" is not an independent clause; it shares the subject "teacher.") This is actually correct if we understand it as: "The teacher [subject] *explained* the lesson [first verb] and [second verb] *solved* the practice problems." (One subject, two verbs joined by "and".) More clearly: "The teacher explained the lesson and solved the practice problems with her class." (Compound predicate, not two independent clauses.) **Method 4: Use a Subordinating Conjunction (Create a Dependent Clause)** If one clause is less important than the other, make it dependent by adding a subordinating conjunction like *because, although, if, when, while, since, as, unless, until.* Example (Fixed): "*Because* the learners completed their assignments, the teacher checked them." (The first clause becomes dependent.) Example (Fixed): "*Although* she studied hard, she did not pass the exam." (Shows contrast.) Example (Fixed): "*When* she studied hard, she passed the exam." (Shows time relationship.) **Comma Splice with an Adverbial Conjunct** When two independent clauses are joined by an adverbial conjunct (however, therefore, nevertheless, moreover, etc.), you must use a semicolon, not a comma. Incorrect (Comma Splice): "She studied hard, however she did not pass." (Comma with adverbial conjunct; needs a semicolon.) Correct: "She studied hard; however, she did not pass." (Semicolon before the adverbial conjunct.) Correct: "She studied hard, but she did not pass." (Comma + coordinating conjunction; "but" is different from "however".) **Faulty Parallelism** **Parallelism** means that items in a series, items being compared, or items joined by a conjunction must have the same grammatical structure. **Faulty parallelism** occurs when items that should be parallel are written in different structures. **Rule 1: Items in a Series** When listing items, all items must have the same grammatical form. Example (Faulty): "She likes *reading, writing,* and *to swim*." (Two gerunds and one infinitive; not parallel.) Corrected: "She likes *reading, writing,* and *swimming*." (All gerunds.) Corrected: "She likes *to read, to write,* and *to swim*." (All infinitives.) Example (Faulty): "The learners solved problems, answered questions, and *were discussing* the answers." (Two simple past verbs and one progressive; not parallel.) Corrected: "The learners *solved* problems, *answered* questions, and *discussed* the answers." (All simple past.) Example (Faulty): "The lesson covered *addition, subtraction, multiplication,* and *how to divide*." (Three nouns and one prepositional phrase.) Corrected: "The lesson covered *addition, subtraction, multiplication,* and *division*." (All nouns.) **Rule 2: Items Joined by Correlative Conjunctions** When using correlative conjunctions (*not only ... but also, either ... or, neither ... nor, both ... and*), the items on each side of the conjunction must be parallel. Example (Faulty): "She is *not only* *intelligent* *but also* *she works* hard." (Adjective vs. clause; not parallel.) Corrected: "She is *not only* *intelligent* *but also* *hardworking*." (Both adjectives.) Example (Faulty): "The teacher *either* *gives* lectures *or* *students read* the textbook." (Active voice vs. passive voice implied; structures differ.) Corrected: "The teacher *either* *gives* lectures *or* *assigns* reading." (Both are actions by the teacher.) Example (Faulty): "*Both* *studying* and *to practice* are essential." (Gerund and infinitive.) Corrected: "*Both* *studying* and *practicing* are essential." (Both gerunds.) **Rule 3: Comparisons** When comparing two things, the items being compared should be parallel. Example (Faulty): "Her grades are higher *than Ana*." (Comparing grades to a person; not parallel.) Corrected: "Her grades are higher *than Ana's* [grades]." (Comparing grades to grades.) Example (Faulty): "The climate here is different *from my previous school*." (Comparing a climate to a school; not parallel.) Corrected: "The climate here is different *from the climate at my previous school*." (Both are climates.) Example (Faulty): "Teaching children is *more challenging than* a textbook." (Comparing an action to an object; not parallel.) Corrected: "Teaching children is *more challenging than* *writing a textbook*." (Both are actions.) **Identifying and Correcting Faulty Parallelism** When you see a sentence with a series, a pair joined by a conjunction, or a comparison, stop and check the grammatical structure of each item: 1. Are all items nouns? Verbs? Phrases? Clauses? 2. Do they all use the same voice (active or passive)? 3. Do they all use the same tense (if verbs are involved)? 4. Are they all phrases of roughly the same length and complexity? If any item deviates from the pattern, the parallelism is faulty. Restructure the sentence so all items match.

The LET tests not only grammar rules but also **word choice**—the ability to select the correct word from among commonly confused pairs. These are words that sound similar, are spelled similarly, or have related meanings but are not interchangeable. Mastering these pairs is essential because a wrong word choice creates an error even if the sentence is grammatically correct. **Affect Versus Effect** **Affect** is primarily a **verb** meaning "to influence" or "to have an impact on." Example: "Poor attendance *affects* academic performance." (The attendance influences the performance.) Example: "The rain *affected* our outdoor activity." (The rain had an impact.) Example: "Does this medicine *affect* the learner's concentration?" (Does it influence?) **Effect** is primarily a **noun** meaning "a result" or "an outcome." Example: "The medicine has a positive *effect* on the learner's concentration." (The result is positive.) Example: "What *effects* did the new curriculum have?" (What results or outcomes?) Example: "The *effects* of climate change are visible." (The results or impacts.) Note: *Effect* can occasionally be a verb meaning "to bring about" or "to cause to happen" (e.g., "to effect change"), but this use is rare and usually appears in formal or technical writing. For the LET, treat *effect* as a noun and *affect* as a verb. Memory aid: "**A**ffect is an **a**ction (verb); **e**ffect is an **e**nd result (noun)." **Fewer Versus Less** **Fewer** is used with **countable nouns** (nouns that can be counted individually: students, books, minutes, errors). Example: "The school has *fewer* teachers this year." (Count: 20 teachers vs. 25 teachers.) Example: "She made *fewer* mistakes on this test." (Count: 5 mistakes vs. 10 mistakes.) Example: "Use *fewer* words in your summary." (Words can be counted.) **Less** is used with **uncountable nouns** (nouns that cannot be separated into individual units: water, sugar, time, information, furniture, luggage). Example: "The assignment requires *less* time than the previous one." (Time cannot be counted as individual units.) Example: "Use *less* sugar in the recipe." (Sugar is uncountable.) Example: "She has *less* confidence than she did before." (Confidence is uncountable.) Example: "The project requires *less* effort this year." (Effort is uncountable.) Memory aid: **F**ewer = **f**igures (countable); **l**ess = **l**arge amounts (uncountable). **Between Versus Among** **Between** is used when referring to **two** people, things, or groups. Example: "The disagreement is *between* the teacher and the principal." (Two people.) Example: "Divide the books *between* the two classes." (Two groups.) Example: "This is a conversation *between* you and me." (Two people.) **Among** is used when referring to **three or more** people, things, or groups. Example: "The discussion was *among* the teachers." (Multiple teachers.) Example: "Distribute the materials *among* all the learners." (More than two.) Example: "*Among* the books on the shelf, this one is most useful." (Multiple books.) Note: *Between* can also be used for a relationship "within a group" in some contexts (e.g., "among themselves" vs. "between themselves"), but for the LET, use "between" for two and "among" for three or more. **Amount Versus Number** **Amount** is used with **uncountable nouns**. Example: "We received a large *amount* of donations." (Donations as a mass; uncountable.) Example: "The *amount* of water wasted is concerning." (Water is uncountable.) Example: "A significant *amount* of work remains." (Work is uncountable.) **Number** is used with **countable nouns**. Example: "A large *number* of learners attended the event." (Learners can be counted.) Example: "The *number* of absences has decreased." (Absences are countable.) Example: "We received a *number* of complaints." (Complaints can be counted.) Memory aid: **A**mount goes with uncountable nouns (water, sugar, time); **n**umber goes with countable nouns (learners, books, minutes). **Lie Versus Lay** (Covered in Verb Tenses, but Repeated Here for Completeness) **Lie** means "to recline" or "to rest." It is **intransitive** (does not take a direct object). Principal parts: lie, lay, lain. Example: "Please *lie* down and rest." (Present.) Example: "She *lay* on the bench yesterday." (Past.) Example: "The book *has lain* on the desk all week." (Present perfect.) **Lay** means "to place" or "to put down something." It is **transitive** (takes a direct object). Principal parts: lay, laid, laid. Example: "Please *lay* the materials on the table." (Present; "materials" is the object.) Example: "He *laid* the foundation for the project." (Past; "foundation" is the object.) Example: "She *has laid* the groundwork." (Present perfect; "groundwork" is the object.) Memory aid: **L**ay = **l**ay down something (transitive); **l**ie = recline (intransitive). The confusion is compounded because the past tense of "lie" (*lay*) looks like the base form of "lay." Always ask: Is there an object? If yes, use a form of "lay"; if no, use a form of "lie." **Rise Versus Raise** (Covered in Verb Tenses, but Repeated Here for Completeness) **Rise** means "to go up" or "to move upward." It is **intransitive** (no object). Principal parts: rise, rose, risen. Example: "The sun *rises* in the east." (Present.) Example: "The water level *rose* after the rain." (Past.) Example: "Prices *have risen* dramatically." (Present perfect.) **Raise** means "to lift up," "to increase," or "to bring up (a child)." It is **transitive** (takes an object). Principal parts: raise, raised, raised. Example: "*Raise* your hand if you know the answer." (Present; "hand" is the object.) Example: "The school *raised* funds for the project." (Past; "funds" is the object.) Example: "We are *raising* awareness about nutrition." (Present progressive; "awareness" is the object.) Memory aid: **R**aise = **r**aise something (transitive); **r**ise = rise on its own (intransitive). **Accept Versus Except** **Accept** is a **verb** meaning "to receive" or "to agree to." Example: "The teacher will *accept* the late submission." (Will receive or agree to it.) Example: "She *accepts* the responsibility." (Agrees to it.) Example: "We *accept* your proposal." (Agree to it.) **Except** is usually a **preposition** meaning "not including" or "with the exclusion of." It can also be a verb (rare) meaning "to exclude." Example: "Everyone came *except* Maria." (Not including Maria.) Example: "All learners completed the task *except* two." (Not including two.) Example: "I like all fruits *except* mangoes." (Not including mangoes.) Example (Verb use, rare): "No one was *excepted* from the rule." (Excluded.) Memory aid: **Acc**ept = **acc**ept or receive; **Ex**cept = **ex**clude. **Principal Versus Principle** **Principal** can be: 1. A **noun** meaning "the head of a school." Example: "The *principal* observed the class." (School administrator.) 2. An **adjective** meaning "main" or "most important." Example: "The *principal* goal of education is to develop learners." (Main goal.) 3. A noun meaning "a sum of money" (finance). Example: "Interest is calculated on the *principal*." (Initial investment.) **Principle** is a **noun** meaning "a fundamental rule," "a code of conduct," or "an underlying truth." Example: "The *principle* of gravity explains why objects fall." (Underlying law.) Example: "She adheres to strong *principles*." (Code of conduct; aligned with RA 7836, the Code of Ethics for Professional Teachers.) Example: "The *principle* of democracy is equality." (Fundamental concept.) Memory aid: **Princip**al ends in **al** (like the word "school") and refers to the school head or is an adjective meaning "main." **Principle** ends in **le** (like the word "rule") and refers to a rule or fundamental concept. **It's Versus Its** (Covered in Pronouns, but Repeated Here for Completeness) **It's** is a **contraction** of "it is." Example: "*It's* a beautiful day." (= "It is a beautiful day.") Example: "*It's* important to practice regularly." (= "It is important...") **Its** is a **possessive pronoun** meaning "belonging to it." Example: "The dog wagged *its* tail." (The tail belongs to the dog.) Example: "The school celebrated *its* anniversary." (The anniversary belongs to the school.) Memory aid: **Its** is possessive (like "his" or "her"); **it's** is a contraction (can be replaced with "it is"). **Their, There, They're** (Covered in Pronouns, but Repeated Here for Completeness) **Their** is a **possessive pronoun** meaning "belonging to them." Example: "The learners brought *their* books." (The books belong to them.) Example: "The teachers submitted *their* reports." (The reports belong to them.) **There** is an **adverb** indicating place or position. Example: "The classroom is over *there*." (In that location.) Example: "There is a meeting at 3 PM." (Introductory word; the true subject is "a meeting.") **They're** is a **contraction** of "they are." Example: "*They're* attending the training." (= "They are attending...") Example: "*They're* ready for the exam." (= "They are ready...") Memory aid: **Their** = possessive; **there** = place; **they're** = contraction of "they are." **Your Versus You're** (Covered in Pronouns, but Repeated Here for Completeness) **Your** is a **possessive pronoun** meaning "belonging to you." Example: "What is *your* name?" (The name belongs to you.) Example: "Submit *your* assignments by Friday." (The assignments belong to you.) **You're** is a **contraction** of "you are." Example: "*You're* doing excellent work." (= "You are doing excellent work.") Example: "*You're* welcome to attend." (= "You are welcome...") Memory aid: **Your** = possessive; **you're** = contraction of "you are." **Other Commonly Confused Pairs** **Loose Versus Lose** - *Loose* (adjective or verb) = not tight; to release: "The screw is *loose*"; "Don't *loose* the dog." (Rare as a verb.) - *Lose* (verb) = to misplace or to be defeated: "Don't *lose* your keys"; "Our team did not *lose* the game." **Quiet Versus Quite** - *Quiet* (adjective or noun) = silent; absence of noise: "Please be *quiet*." (The learners must be quiet.) - *Quite* (adverb) = rather; fairly; to a considerable extent: "The lesson was *quite* difficult." (Rather difficult.) **Sight, Site, Cite** - *Sight* (noun or verb) = vision; something seen: "The view is a beautiful *sight*." - *Site* (noun) = a place or location: "The construction *site* is near the school." - *Cite* (verb) = to mention or quote: "Please *cite* your sources." (Provide references.) **Stationary Versus Stationery** - *Stationary* (adjective) = not moving; staying in one place: "The learner remained *stationary* during the demonstration." - *Stationery* (noun) = writing materials (paper, envelopes, etc.): "The school purchases classroom *stationery*."

The LET's error-identification item format is distinctive: a sentence is divided into four underlined parts labeled A, B, C, and D. Your task is to identify the part containing an error, or mark "No error" if the sentence is correct. This section teaches a systematic approach to solving these items efficiently and accurately. **The Error-Identification Format** Example Item: "The teacher, (A) *together with her students*, (B) *were preparing* the props (C) *carefully* (D) *for* the school play." Choices: a) A b) B c) C d) D e) No error In this example, the error is in part B. The subject is "teacher" (singular, not "students"), so the verb should be "was preparing," not "were preparing." **The Systematic Checking Strategy** When faced with an error-identification item, apply this **four-step checking order**: **Step 1: Check the Verb (Subject-Verb Agreement and Tense)** The verb is the highest-frequency error, so check it first: - Does the verb agree with its subject in number? (Ignore intervening phrases.) - Is the tense correct and consistent with the rest of the sentence? - If it is an irregular verb, is the form correct (lie/lay/lain, rise/raise, sit/set, etc.)? - Is it a linking verb? If so, should it be followed by an adjective, not an adverb? If you find an error in the verb, mark that part and move on; there is usually only one error per sentence. If the verb is correct, proceed to Step 2. **Step 2: Check Pronouns (Case and Reference)** Check every pronoun for: - **Case:** Is it subjective, objective, or possessive as appropriate? After a preposition, is it objective? - **Reference:** Does the pronoun have a clear, unambiguous antecedent? - **Agreement:** Does the pronoun agree with its antecedent in number, gender, and person? If you find a pronoun error, mark that part. If all pronouns are correct, proceed to Step 3. **Step 3: Check Modifiers (Adjective/Adverb, Placement, and Dangling)** Check all modifiers: - **Adjective versus adverb:** After a linking verb, is an adjective used? After an action verb, is an adverb used? - **Placement:** Is the modifier placed next to the word it modifies? - **Dangling:** Does a participial phrase at the start of the sentence have a clear subject to modify? - **Comparison:** If comparing, are the items parallel? Is the correct comparative/superlative form used (two vs. three or more)? If you find a modifier error, mark that part. If all modifiers are correct, proceed to Step 4. **Step 4: Check Idiom and Word Choice** Check for: - **Prepositions:** Is the correct preposition used (agree with, agree to, agree on, etc.)? - **Articles:** Is *a/an* used correctly (by sound, not spelling)? Is *the* used when needed? - **Confusable pairs:** Are easily confused words (affect/effect, fewer/less, between/among, lie/lay, accept/except, etc.) used correctly? - **Parallelism:** In a series, are all items parallel in structure? If you find an error in idiom or word choice, mark that part. If no errors are found after all four steps, the answer is "No error." **Practical Tips for Error-Identification** 1. **Read the entire sentence carefully before checking.** Many errors are designed to be missed by readers who focus only on the underlined parts or who jump to conclusions. Read the whole sentence to understand its meaning and structure. 2. **Ignore the temptation to "hear" the correct answer.** Some sentences sound natural even when they contain grammatical errors. Instead, apply the rules you have learned. 3. **Watch for intervening phrases.** A phrase between the subject and the verb often baits test-takers into using the wrong verb number. For example: "The team of players *are* skilled." The subject is "team" (singular), not "players," so the correct verb is "is," not "are." 4. **Look for ambiguous pronouns.** Sentences like "When Maria met Ana, *she* was nervous" are deliberately ambiguous. Pronouns with unclear antecedents are errors. 5. **Notice modifier placement issues.** Sentences like "She served sandwiches to the children on paper plates" appear correct on first reading, but the modifier "on paper plates" is misplaced and creates confusion. 6. **Check for tense shifts.** If a sentence begins in past tense but shifts to present, it is usually an error unless there is a clear reason for the shift. 7. **Be cautious of absolute adjectives.** Words like "unique" and "perfect" cannot be compared. "More unique" is an error. 8. **Remember that "No error" is a valid and sometimes correct answer.** Not every sentence contains an error. If you have checked all four areas and found nothing wrong, mark "No error" with confidence. **Worked Examples** Example 1: "The principal, (A) *along with the teachers*, (B) *have* planned (C) *an* assembly (D) *for* next week." Step 1 (Verb): Check the verb "have." The subject is "principal" (singular), not "teachers." The phrase "along with the teachers" is intervening and does not change the subject. The correct verb should be "has," not "have." Error found in part B. Answer: b) B Example 2: "The teacher explained (A) *the* lesson (B) *carefully* to (C) *he* and (D) *I*." Step 1 (Verb): The verb "explained" agrees with the subject "teacher" and is in the correct tense. No error. Step 2 (Pronouns): Check "he" and "I." Both are objects of the preposition "to," so they should be in the objective case: "him" and "me." Error found in part D (and part C). But since you can mark only one error, choose the first one you encounter in reading order, which is part C. Answer: c) C (or d) D, depending on which is marked first in the item) Note: In a real exam, if both C and D contain errors, the item may be flawed or may expect you to mark the "first" error. Always mark the error you find first when checking in order. Example 3: "Among the three candidates, Maria is (A) *the* most (B) *qualified* (C) *teacher* (D) *for* the position." Step 1 (Verb): "is" is correct (linking verb). Step 2 (Pronouns): No pronouns present. Step 3 (Modifiers): Check "most qualified." This is a superlative, which is correct because we are comparing three candidates (three or more). No error. Step 4 (Idiom): "For the position" is correct; "qualified for" is the right idiom. No error found. Answer: e) No error Example 4: "The learners (A) *having* completed (B) *their* assignments, (C) *the* teacher (D) *reviewed* the answers." Step 1 (Verb): "completed" and "reviewed" are both correct. Step 2 (Pronouns): "their" is correct; it refers to "learners." Step 3 (Modifiers): Check the participial phrase "having completed their assignments." The subject performing this action should be "the learners." But the main clause subject is "the teacher," not the learners. This is a dangling modifier. Error found in part A (or the overall structure is flawed). However, if the focus is on the underlined parts, part A contains the participial phrase. Answer: a) A Example 5: "She (A) *prefers* reading (B) *than* writing, (C) *especially* in (D) *the* evening." Step 1 (Verb): "prefers" is correct. Step 2 (Pronouns): "She" is correct. Step 3 (Modifiers): "especially" (adverb) modifies the verb and is correctly placed. Step 4 (Idiom/Word Choice): Check "prefers reading than writing." The correct idiom is "prefer X *to* Y," not "prefer X *than* Y." Error found in part B. Answer: b) B **Common Error Patterns on the LET** Based on years of test analysis, these patterns appear frequently: 1. Subject-verb agreement with intervening phrases (e.g., "box of books") 2. Pronoun case after prepositions (e.g., "between you and *me*") 3. Adjective/adverb confusion after linking verbs (e.g., "feels *good* vs. feels *well*") 4. Dangling modifiers at the start of sentences 5. Misplaced modifiers creating ambiguity 6. Tense inconsistency (shifting from past to present without reason) 7. Word-choice pairs (affect/effect, fewer/less, lie/lay) 8. Comparison errors (more taller, more unique) 9. Idiomatic prepositions (agree with, agree to, agree on) 10. Pronoun reference ambiguity ("When Maria met Ana, she...") Familiarity with these patterns will help you spot errors quickly during the exam.
