Adjective clauses modify nouns and pronouns. They usually follow the word they modify and often begin with subordinating words like who, which, that, when, where, etc. Examples include "The store manager, who is in charge of produce, inspected the apples" and "The store where we bought the shoes closed recently." Sometimes the subordinating word can be excluded as in "There is one place (that) I intend to visit." Adjective clauses provide more details about the noun they modify.
