Subject-Verb Agreement
Subject-verb agreement means that the sentence is grammatically correct.
Subject-verb agreement is usually more of a problem in present-tense sentences. Verbs in the past tense don’t change as much when the number of the subjects change (“He talked” is the same verb form as “They talked,” for example).
The subject and verb within a sentence need to agree with each other in number in order for a sentence to make sense.
