Subject/Verb agreement

Subject/verb agreement means that the subject and verb in a sentence must match in number. If the subject is singular, the verb must be singular; if the subject is plural, the verb must be plural.

The correct verb form for a singular subject is usually the base form of the verb with an 's' added in the present tense (e.g., he plays, she runs).

The correct verb form for a plural subject is the base form of the verb without an 's' (e.g., they play, we run).

The cat sits on the mat.

The dogs run in the park.

She walks to school every day.

The teacher explains the lesson.

My friends go to the movies.

Use 'plays' when the subject is singular (e.g., he plays, she plays).

Use 'play' when the subject is plural or when using 'I' or 'you' (e.g., they play, I play, you play).
