Introduction to Subject-Verb Agreement
Notes
Foundation slide introducing the core concept
Examples
- Cardo runs. (singular subject + singular verb)
- Teachers record the scores. (plural subject + plural verb)
Subject-verb agreement means that singular subjects take singular verbs, and plural subjects take plural verbs. This rule ensures grammatical correctness and clarity in communication.
Main points
- Definition: Unity of verb and subject in person and number
- Applies primarily to present tense verbs
- Also applies to past forms of 'to be' (was, were)
- Essential for clear communication
- Frequently tested in CSE and other professional exams

Person and Number Agreement
Notes
Explains the systematic approach to person-number agreement
Examples
- I am studying. (first person singular)
- You are welcome. (second person)
- She has her way of thinking. (third person singular)
- They have their opinions. (third person plural)
The verb must agree with its subject not only in number (singular/plural) but also in person (first, second, third). Each person has specific verb forms that must be matched correctly.
Main points
- First person: I, we
- Second person: you (singular and plural)
- Third person: he, she, it, they
- Singular subjects take singular verbs
- Plural subjects take plural verbs

Simple Subject Rule
Notes
Critical rule for avoiding common mistakes in subject identification
Examples
- The box of pencils belongs on my desk. (subject: box)
- The woman, who sings in fields, scares them. (subject: woman)
- A container of nuts and bolts was found. (subject: container)
The simple subject is the main noun or pronoun that performs the action. Modifying phrases, prepositional phrases, and clauses do not affect the verb form.
Main points
- Only the simple subject determines verb number
- Ignore modifying phrases and clauses
- Cross out prepositional phrases to find the subject
- Focus on the head noun in noun phrases
- Don't be misled by words between subject and verb

Three Types of Verbs
Notes
Foundation for understanding how different verb types behave in agreement
Examples
- Main: Lina dances on the street.
- Auxiliary: We are sitting on the couch.
- Modal: The dog cannot swim very well.
Understanding the three types of verbs helps in applying agreement rules correctly. Each type has specific patterns for subject-verb agreement.
Main points
- Main verbs: carry meaning, can stand alone
- Auxiliary verbs: helping verbs (do, have, be)
- Modal verbs: show how action is performed
- Auxiliary verbs change form based on subject
- Modal verbs always use base form of main verb

Tricky Sentence Structures: Expletives
Notes
Common error area in exams - students often mistake expletives for subjects
Examples
- There were five men walking down the street. (subject: five men)
- Here is my gift for you. (subject: gift)
- There are many students in the classroom. (subject: students)
Expletive constructions reverse normal word order. The words 'there' and 'here' signal that the actual subject follows the verb, not precedes it.
Main points
- There is/are and Here is/are constructions
- There and Here are NOT the subjects
- Real subject comes after the verb
- Use singular verb with singular subject after expletive
- Use plural verb with plural subject after expletive

Reversed Order and Interrogative Sentences
Notes
Essential skill for handling complex sentence structures in exams
Examples
- Among the ingredients is sugar. → Sugar is among the ingredients.
- Is your house ready? → Your house is ready.
- Who won the competition? (Who is the subject)
When normal subject-verb order is reversed, rearranging the sentence helps identify the true subject and apply correct agreement rules.
Main points
- Subject may come after main verb in reversed order
- Rearrange sentence to find subject easily
- In questions, subject is between helping and main verb
- Convert interrogative to declarative to find subject
- Question words (who, what, which) can be subjects
Diagram

Imperative and Passive Sentences
Notes
Special cases that require different approaches to subject identification
Examples
- Listen to me! (You listen to me!)
- Please turn right. (You please turn right.)
- The app was recognized for excellence. (app receives recognition)
Imperative sentences have an implied subject 'you' even when not stated. Passive sentences change the typical subject-verb relationship by making the subject the receiver of action.
Main points
- Imperatives have understood subject 'you'
- Commands and requests are imperatives
- Imperatives take plural verb forms
- In passive sentences, subject receives the action
- Subject is acted upon, not performing action

Compound Subjects with Conjunctions
Notes
Complex but frequently tested area requiring careful attention to conjunction type
Examples
- John and Pete get into a fight. (plural)
- Bacon and egg is my favorite breakfast. (single unit)
- Either the teacher or students are ready. (nearest: students)
- Maria, not Juan, is the smart one. (positive: Maria)
Different conjunctions create different agreement patterns. Understanding these patterns is crucial for correct verb selection with multiple subjects.
Main points
- Subjects joined by 'and' are usually plural
- Exception: compound subjects forming single unit are singular
- With 'or', 'nor', 'either...or', 'neither...nor': match nearest subject
- Phrases like 'as well as', 'together with' don't create compounds
- Positive-negative compounds: match positive subject

Indefinite Pronouns - Singular Group
Notes
Memorization aid for the most commonly confused indefinite pronouns
Examples
- Everybody wants to attend the webinar.
- Each of them does have contributions.
- No one is taking responsibility.
- Something is wrong with the system.
These indefinite pronouns are always treated as singular, even when they seem to refer to multiple people or things. This is a frequent source of errors in writing.
Main points
- Always singular: each, every, either, neither
- Singular: everyone, everybody, someone, somebody
- Singular: anyone, anybody, no one, nobody
- Singular: everything, something, nothing, anything
- All take singular verb forms
Diagram

Indefinite Pronouns - Plural and Variable
Notes
Critical distinction between always-plural and context-dependent pronouns
Examples
- Many of the participants prefer online training. (always plural)
- Most of the students are in favor. (plural - countable)
- Most of the water is clean. (singular - uncountable)
Some indefinite pronouns are always plural, while others change based on what follows them. The key is identifying whether the 'of' phrase refers to something countable or uncountable.
Main points
- Always plural: both, few, many, several
- Variable: all, any, most, none, some
- Variable pronouns depend on following 'of' phrase
- If 'of' phrase refers to countable plural: use plural verb
- If 'of' phrase refers to uncountable: use singular verb

Collective Nouns and Special Cases
Notes
Requires understanding context and meaning to choose correct verb form
Examples
- The team is traveling to Manila. (as one unit)
- The team are arguing about strategy. (individual members)
- My family prefers vegetables. (unified preference)
Collective nouns can be tricky because they refer to groups that can act either as single units or as collections of individuals. The verb choice depends on the intended meaning.
Main points
- Collective nouns: team, family, class, group, committee
- Singular when acting as single unit
- Plural when members act individually
- Context determines the correct interpretation
- Consider the meaning, not just the form

Measurement, Money, Time, and Distance
Notes
Important exception to normal plural rules - quantity as single concept
Examples
- Twenty-five miles is too far to walk.
- Five hundred thousand pesos is much money.
- Seven PM is a good time for dinner.
- Four kilograms of oil is required.
When expressions indicate quantity, amount, or measurement as a unit, they are treated as singular regardless of the plural form of the words used.
Main points
- Expressions of quantity treated as single units
- Money amounts: always singular
- Time periods: always singular
- Distances: always singular
- Mathematical expressions: always singular

The Number vs A Number
Notes
Frequently tested rule that requires memorization of the distinction
Examples
- The number of chairs lined up was five hundred.
- A number of fruits were displayed on the table.
- The variety of flowers is amazing.
- A variety of problems were discussed.
This is a specific rule that must be memorized. The definite article 'the' makes the expression singular, while the indefinite article 'a' makes it plural.
Main points
- 'The number' always takes singular verb
- 'A number' always takes plural verb
- Same pattern for 'the variety' vs 'a variety'
- Article choice determines verb agreement
- Memorize this distinction for exams
Diagram

Special Plural and Singular Nouns
Notes
Irregular cases that require memorization rather than rule application
Examples
- My glasses are missing. (always plural)
- The news was disheartening. (singular meaning)
- Mathematics is required for engineering. (subject field)
- The equipment is expensive. (noncount noun)
Some nouns have irregular patterns for subject-verb agreement. These exceptions must be learned individually as they don't follow standard rules.
Main points
- Always plural: scissors, pants, glasses, pliers
- Plural form, singular meaning: news, mathematics, economics
- Subject fields ending in -s: usually singular
- Noncount nouns: always singular
- Titles of works: always singular

Common Errors and Exam Tips
Notes
Practical strategy for exam success and error avoidance
Examples
- Wrong: The list of books were made by Denzel.
- Right: The list of books was made by Denzel.
- Wrong: There's many problems to solve.
- Right: There are many problems to solve.
Success in subject-verb agreement requires avoiding common traps and applying systematic approaches to identify subjects and match appropriate verbs.
Main points
- Don't be misled by intervening phrases
- Identify the simple subject first
- Watch for reversed word order
- Remember collective noun contexts
- Practice with indefinite pronouns
