A dependent clause can function as an adjective in a sentence structure.
A dependent clause is a group of words containing a subject and a verb that relies on an independent clause to form a complete sentence. In sentence structure, a dependent clause can act as an adjective by modifying a noun or pronoun within the sentence. For example, in the sentence 'The house that Jack built is big,' the clause 'that Jack built' is acting as an adjective describing the noun 'house'.
