Do All Sentences Have a Predicate?

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. ... The predicate (which always includes the verb) goes on to relate something about the subject: what about the audience?

Can a sentence not have a predicate?

The verb and everything attached to it is the predicate. So if it doesn't have a predicate, and it's not imperative, it's not a sentence. If you have a standalone group of words with a missing subject or predicate, that would be a sentence fragment.

Do simple sentences always have a predicate?

A simple sentence contains one independent clause. ... Put another way: a simple sentence contains a subject and a predicate, but a compound sentence contains more than one subject and more than one predicate.
