Let's dive right into some different adjective clause examples. As soon as you see adjective clauses in action, you'll be able to spot them from a mile away. Advertisement Adjective Clauses in Action Adjective clauses don't usually change the basic meaning of a sentence; they just add more information. Adjective clauses are used to describe a noun in the main sentence. In the example above, the adjective clause tells us about "the man." Just ignore the main sentence and look at the adjective clause when deciding whether to use "who," "whom" or "whose." Ask yourself if the adjective clause requires a subject, object, or possessive form. V2gc0.
