What Is Subject-Verb Agreement?
Subject-verb agreement means that the subject and the verb in a sentence must match in number and person.
- Singular subjects take singular verbs.
- Plural subjects take plural verbs.
Example:
- The cat runs fast. (Singular)
- The cats run fast. (Plural)
Think of it as a “teamwork rule”: the subject and the verb must work together.
Why Subject-Verb Agreement Matters
Correct subject-verb agreement:
- Makes sentences clear and professional.
- Prevents confusion for readers.
- Helps in academic writing, emails, and reports.
Incorrect example:
- The group of students is going to the library. (Correct)
- The group of students are going to the library. (Incorrect unless referring to individuals acting separately)
Basic Rules of Subject-Verb Agreement
Here are the most important rules to follow:
1. Singular and Plural Subjects
- Singular subject → Singular verb
- Plural subject → Plural verb
Examples:
- She writes daily.
- They write daily.
2. Verb “Be” Conjugation
The verb be changes according to person and number:
| Person | Singular | Plural |
|---|---|---|
| First | I am | We are |
| Second | You are | You are |
| Third | He/She/It is | They are |
Examples:
- I am happy.
- She is a doctor.
- They are friends.
3. Compound Subjects
Subjects joined by “and” → plural verb
- Tom and Jerry are playing.
Subjects joined by “or” / “nor” → verb agrees with nearest subject
- Either the teacher or the students have the answer.
- Neither the students nor the teacher is present.
4. Indefinite Pronouns
Some pronouns are always singular: anyone, everyone, someone, nobody, each
- Example: Everyone is welcome.
Some pronouns are always plural: both, few, several
- Example: Both of the cats are sleeping.
5. Collective Nouns
A collective noun can be singular or plural depending on context:
- Singular (acting as a unit): The team is winning.
- Plural (individual members acting separately): The team are arguing among themselves.
6. Expressions of Time, Money, and Distance
Treated as singular when considered as a whole:
- Five dollars is enough.
- Ten years is a long time.
Plural if counted separately:
- Two hours have passed.
- Fifty dollars are in small bills.
7. Titles, Books, and Movies
Singular titles → singular verb
- The Lord of the Rings is amazing.
Plural titles → plural verb
- The Harry Potter movies are popular.
8. Sentences Beginning with Here / There
Verb agrees with the subject after the verb
- Here comes the bride.
- There are five books on the table.
9. Gerunds and Infinitives as Subjects

- Swimming is fun.
Infinitives (to + verb) → singular verb
