Adverb Clauses

Adverb clauses modify single words (verbs, adjectives, or adverbs) or entire phrases or clauses. They always begin with a subordinating conjunction. Adverb clauses answer the questions how? where? when? why? and to what extent? Adverb clauses appear in any of several places in the sentence as long as the relationship is clear and its position conveys the intended purpose.

Example:
Confused, after class was over, Susan decided to meet with her group to discuss the paper.
(An adverb clause modifies the participle confused.)
