Essential and Nonessential Adjective Clauses. Remember that an adjective clause is a dependent clause that acts like an adjective in the sentence. This means that it gives more information about a noun or pronoun in the sentence. Sometimes the information given by the adjective clause is essential. An essential adjective clause is one that is needed for the sentence to make sense. If you took it out, you would not know all the information that you need to know. At other times, the information given by the adjective clause is nonessential.
