What is the difference between the subject and predicate of a sentence?
1) One asks a question and the other provides an answer.
2) One names the doer and one names the action done.
3) One is required to make a complete sentence while the other is not.
4) One relates to the protagonist and the other to the story’s villain.
Every complete sentence contains two parts: a subject and a predicate. The subject is what (or whom) the sentence is about, while the predicate tells something about the subject.
