Adverb Clauses
A clause is a group of related words which has both a subject and a predicate. A clause is different from a phrase because a phrase is a group of related words which lacks either a subject or a predicate or both.
Adverb clauses usually modify verbs, in which case they may appear anywhere in a sentence. They tell why, where, under what conditions, or to what degree the action occurred or situation existed. Unlike adjective clauses, they are frequently movable within the sentence.
Example:
When the timer rings, we know the cake is done.
We know the cake is done when the timer rings.
Adverb clauses always begin with a subordinating conjunction. Subordinating conjunctions introduce clauses and express their relation to the rest of the sentence.
