What is the difference between a subordinate clause and a complement?

A subordinate clause is a group of words that contains a subject and a predicate, but it is not a complete sentence. A complement is a word or phrase that is added to a sentence to provide more information.

A subordinate clause can be a clause, a phrase, or a noun phrase. A complement can be a noun, pronoun, or adjective.

Subordinate clauses are used to provide more information about a main clause. Complements are used to provide additional information about a noun or pronoun.
