Grammar — Subject-Verb Agreement

Every sentence has two key parts: the subject (who or what the sentence is about) and the verb (the action or state). The verb must always agree with the subject in number — this is called subject-verb agreement.

What this lesson teaches

1Identify the subject of a sentence and decide whether it is singular or plural
2Add -s or -es to a present tense verb when the subject is singular (he, she, it, or a singular noun)
3Use the base form of the verb when the subject is plural (they, we, I, or a plural noun)
4Correct common subject-verb agreement errors in sentences
5Recognize that 'I' takes the base form of the verb even though it is singular
