Subject verb agreement

Subject-verb agreement means that the verb in a sentence must agree in number with its subject. If the subject is singular, the verb must be singular. If the subject is plural, the verb must be plural.

For example:

• "The dog barks." (Singular subject "dog" with singular verb "barks")
• "The dogs bark." (Plural subject "dogs" with plural verb "bark")

Common errors occur with compound subjects, collective nouns, and indefinite pronouns.
