Subject-verb agreement is a grammatical rule that states the subject of a sentence must agree with its verb in both number and person. Here are the basic principles:
-
Singular subjects take singular verbs:
- Example: The cat runs fast. (singular subject "cat" with singular verb "runs")
-
Plural subjects take plural verbs:
- Example: The cats run fast. (plural subject "cats" with plural verb "run")
-
Compound subjects:
- When two subjects are joined by "and," they typically take a plural verb:
- Example: The dog and cat play together.
- When joined by "or" or "nor," the verb agrees with the subject closest to it:
- Example: Either the teacher or the students are going.
- Example: Neither the students nor the teacher is available.
- When two subjects are joined by "and," they typically take a plural verb:
-
Indefinite pronouns:
- Some indefinite pronouns are always singular (e.g., anyone, everyone, someone):
- Example: Everyone loves a good story.
- Some are always plural (e.g., few, many, several):
- Example: Many are called, but few are chosen.
- Others can be singular or plural depending on context (e.g., all, some):
- Example: All of the cake is gone. (singular)
- Example: All of the cookies are gone. (plural)
- Some indefinite pronouns are always singular (e.g., anyone, everyone, someone):
-
Collective nouns:
- Collective nouns (e.g., team, group, family) can take either a singular or plural verb based on whether the group is acting as a single unit or as individuals:
- Example: The team wins the championship. (acting as one)
- Example: The team are arguing among themselves. (acting as individuals)
- Collective nouns (e.g., team, group, family) can take either a singular or plural verb based on whether the group is acting as a single unit or as individuals:
-
Titles, names, and amounts:
- Titles of books, names of organizations, and amounts are typically treated as singular:
- Example: The team is winning.
- Example: Five dollars is a fair price.
- Titles of books, names of organizations, and amounts are typically treated as singular:
