Which statement is NOT true about relative clauses?

The statement that is NOT true about relative clauses is that a relative clause expresses a complete thought and can stand alone. Relative clauses do not form complete thoughts on their own; instead, they function as part of a larger sentence, providing additional information about a noun. They rely on the main clause for context and meaning.

For example, in the sentence "The book that I borrowed was interesting," the relative clause "that I borrowed" cannot stand alone as a complete sentence as it does not convey a full idea without the main clause. Relative clauses are essential in connecting and adding detail to the main idea, thereby functioning effectively within the broader structure of the sentence.
