This document provides information on different types of adjective clauses and how to use them properly. It discusses adjective clause pronouns used as subjects and objects, as well as expressions like whose, where, when, and quantities. Guidelines are given for punctuation of adjective clauses. In general, adjective clauses add additional identifying or descriptive information about a noun, and pronouns and prepositions within the clause depend on whether the pronoun is serving as the subject or object.
