How is a relative clause verb used in a sentence?

A relative clause verb is used in a sentence to provide additional information about the subject or object of the main clause. It functions as a modifier and is introduced by a relative pronoun (such as who, which, that) or a relative adverb (such as when, where, why). The relative clause verb helps to define or describe the noun it is modifying and adds more detail to the sentence.
