Subject Verb Agreement
In the present tense, verbs agree with their subjects in number, (singular or plural), and in person, (first ,second, or third). The present tense ending -s is used on a verb if its subject is third person singular; otherwise the verb takes no ending. The verb “be” varies from this pattern, and alone among verbs it has special forms in both the present and past tense.
