This document discusses subject-verb agreement and provides examples. It defines the subject as the person, place, thing or idea doing or being something in a sentence. A subject can be singular, plural, or uncountable. It defines the verb as the word describing the action. Verbs can be singular or plural. The key rule is that subjects and verbs must agree in number - a singular subject takes a singular verb and a plural subject takes a plural verb.
