Adverb Clauses Worksheets - 15 Worksheets Library - Free Printable

Let's solve each sentence by adding an adverb clause that answers the question in parentheses. An adverb clause is a group of words that contains a subject and a verb and functions as an adverb, modifying a verb, adjective, or another adverb. It usually begins with a subordinating conjunction (like *when*, *where*, *how*, *because*, etc.).
