Question

Identify the subordinate clause.

Answer 1

A subordinate clause (or dependent clause) is a clause that cannot stand alone as a complete sentence because it does not express a complete thought.

Like all clauses, a subordinate clause has a subject and verb.

Answer 2

It is easy to spot a subordinate clause in a sentence because a subordinate clause begins with a subordinate conjunction or a relative pronoun.  

Relative pronouns are that, which, whichever, who, whoever, whom, whomever, whose.  

Here are some subordinate conjunctions:

after, although, as, because,  before, even if, even though, if, in order that, once, provided that, rather than, since, so that, than, that,  though, unless, until, when, whenever, where, whereas, wherever, whether, while, why.
