What is the function of a clause in a sentence?

A clause is a group of words that contains a subject and a predicate. The subject is the noun or pronoun that performs the action of the verb. The predicate is the verb that expresses the action of the subject.

A clause can be a simple sentence, such as "John went to the store," or a complex sentence, such as "John went to the store and bought some groceries."

A clause is an essential part of a sentence. It provides the information that is needed to make a complete thought. Without clauses, a sentence would be meaningless.
