Step-by-step explanation:
Subordinate clauses are clauses that cannot stand alone as a sentence. Every sentence contains a subject and predicate and expresses a complete thought. Subordinate clauses lack one or more of these elements.
Adjective clauses are subordinate clauses that function as adjectives, which means that they modify nouns.
Adverb clauses are subordinate clauses that function as adverbs, which means that they modify verbs, adjectives, or other adverbs.
Noun clauses are subordinate clauses that function as nouns, which means that they play the role of the subject, direct object, indirect object, predicate nominative, or the object of a preposition.
