Subject-Verb Agreement
Subject-Verb Agreement
Subject-verb agreement means that the subject and verb in a sentence must agree in number—both must be singular or both must be plural. Here are some key rules, with examples for clarity:
1. Singular Subjects with Singular Verbs
- If the subject is singular, the verb should be singular.
- Example: "The dog barks loudly."
Here, "dog" is a singular subject, so we use the singular verb "barks."
2. Plural Subjects with Plural Verbs
- If the subject is plural, the verb should be plural.
- Example: "The dogs bark loudly."
Here, "dogs" is a plural subject, so we use the plural verb "bark."
3. Subjects Joined by "And" Require a Plural Verb
- When two or more subjects are joined by "and," use a plural verb.
- Example: "John and Sarah are attending the concert."
"John and Sarah" are two subjects, so we use the plural verb "are."
4. Singular Subjects Joined by "Or" or "Nor" Take a Singular Verb
- When two singular subjects are joined by "or" or "nor," use a singular verb.
- Example: "Either the teacher or the student is responsible."
5. When a Singular and a Plural Subject Are Joined by "Or" or "Nor"
- The verb should agree with the subject closest to it.
- Example: "Either the students or the teacher has the keys."
Here, "teacher" is singular and closer to the verb, so we use the singular verb "has."
6. Indefinite Pronouns as Subjects
- Indefinite pronouns like everyone, each, nobody, and anyone are singular and take singular verbs.
- Example: "Everyone enjoys the festival."
"Everyone" is singular, so we use the singular verb "enjoys."
7. Collective Nouns (e.g., team, family, group)
- Collective nouns are usually singular in form but represent a group, so they take a singular verb.
- Example: "The team is ready for the match."
"Team" is a collective noun and takes the singular verb "is."
8. "There is" and "There are" Constructions
- Use "is" when the noun following it is singular and "are" when it is plural.
- Example: "There is a book on the table."
- "There are books on the table."
By following these rules, you ensure correct subject-verb agreement, making sentences grammatically accurate and easier to understand.
