Pronouns take the place of nouns when we write or speak. Not all of these parts need to be in a subject, but all of them may be. Every predicate must have a verb. Verbs also tell us when something happens or exists - in the past, the present or the future. They describe when, where, why or how something happens.
Adverbs can also modify adjectives and other adverbs.
Different pronouns are used in the predicate than are used in the subject. Subject Pronouns do it and Predicate Pronouns receive it. Examples of Predicates. Yesterday, Harvey and Harriet took their children to the zoo. The elephants, the lions, and all of the other animals were hungry.
