Answer:
A subordinate conjunction typically introduces an adjective clause.
Step-by-step explanation:
These conjunctions include words such as "who," "whom," "whose," "which," and "that." Adjective clauses are also sometimes introduced by relative pronouns, such as "who," "whom," "whose," "which," and "that." These clauses provide additional information about a noun or pronoun in the sentence and function as adjectives.
For example: "The book, which was written by a famous author, became a bestseller." In this sentence, "which" introduces the adjective clause "which was written by a famous author," which provides additional information about the noun "book."
