Subject-Verb Agreement Overview

Overview

This lesson explains subject–verb agreement in English, highlighting core rules, common exceptions, and tricky cases in writing and speaking.

Core Rule: Subjects and Verbs Must Match

• Plural subjects use plural verbs; singular subjects use singular verbs.
• Plural nouns often add S; singular present verbs for he/she/it add S.
• Example: The cars look expensive. The car looks expensive.

I/You Exception

• I and you are singular but take plural verb forms.
• Examples: I like to swim. You like to swim.
• Third-person singular takes S: She likes to swim.

Present Tense Patterns

• Nouns add S for plural; verbs add S for third-person singular.
• Opposite pattern: plural noun + base verb; singular noun + S verb.

Auxiliary Verbs: Agreement Shifts

• The auxiliary agrees with the subject in complex tenses.
• Present simple do/does: The dogs don’t want it. The dog doesn’t want it.
• Be in progressive: We are going. He is going.
• Have/has in perfect: They have been driving. Anna has been driving.

Modal Verbs: No S on Main Verb

• Modal + base verb; never add S to the following verb.
• Examples: My friend might come. He should come.

Indefinite Pronouns

• Usually singular and take singular verbs.
• Examples: Everybody wants to be loved. Nobody likes being left out.

Compound Subjects

• A and B (with and) = plural subject; use plural verb.
• Example: My mum and dad are proud of me.

Or/Nor with Singular Choices

• A or B (singular options) = singular subject; use singular verb.
• Example: Peter or Paul is coming.
• A and B are coming is plural.

Gerunds and Gerund Phrases

• Single gerund subject = singular verb.
• Examples: Playing football is fun. Waiting for the bus is annoying.
• Gerunds linked by and = plural verb: Meeting friends and going to the beach are favorites.

Collective/Group Nouns

• Can be singular (group as a unit) or plural (members as individuals).
• Singular unit: The team is organising the event.
• Individuals: The team are meeting today.
• Plural groups: The teams are meeting today.

Uncountable and Singular-Looking Plurals

• Uncountable nouns take singular verbs: The furniture is comfortable.
• Words like news are singular: The news is interesting.

Finding the Subject in Complex Sentences

• In questions, identify the true subject before choosing the verb.
• Example: What are the steps we need to follow? Steps = plural, use are.
• There is/there are: match verb to the real subject.
• Example: There are many plants. There is a plant.

Relative Clauses and Noun Phrases

• Ignore extra clauses when matching subject and verb.
• Relative clause example: The car, which belongs to my brother, is not clean.
• Noun phrase example: The new features of the car are impressive.

Summary Table of Key Patterns

Speaking Focus: Final Consonants

• Pronounce final sounds clearly to show agreement in speech.
• Practise contrasts like do vs. does; hits vs. hit; likes vs. like.

Key Terms & Definitions

• Subject–verb agreement: Matching verb form to subject number/person.
• Auxiliary verb: Helping verb that carries agreement (do/does, am/is/are, have/has).

Action Items / Next Steps

• Review and memorise exceptions: I/you forms and modal verb rules.
• Practise identifying subjects in questions, there is/are, and relative clauses.
• Drill pronunciation of final consonants in aligned verb forms.
• Write sample sentences for each pattern and check agreement.
