what is a predicate and subject
The predicate is that part of a sentence which tells something about the subject. e.g. A simple predicate (or verb) describes the action or condition of the subject or subjects in a sentence. e.g.
Subjects tell the listener and the reader whom or what the sentence is about. The subject is that part of a sentence which names a person, thing, or idea. e.g. Every complete subject contains a simple subject. The simple subject, which is a noun or pronoun, is the most important word in the complete subject.
