LET Secondary 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: "Affect is an action (verb); effect is an end 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: Fewer = figures (countable); less = large 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: Amount goes with uncountable nouns (water, sugar, time); number 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: Lay = lay down something (transitive); lie = 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: Raise = raise something (transitive); rise = 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: Accept = accept or receive; Except = exclude.

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: Principal 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.
