Adverb Clauses–Clauses That Give us More Information about Verbs
As you may know, an adverb modifies or describes a verb, and adjective, or another adverb. A clause is a group of words containing a subject and a verb. Some clauses are called adverb causes because they function as adverbs. This means that they describe, modify, or give us more information about the verb in the sentence. In this posting I talk about types of adverb clauses and how to form them. You will see many example sentences. The download at the end will give you more practice using these clauses.
What are adverb clauses?
Adverb clauses are dependent clauses. That means that an adverb clause cannot stand along as a sentence. It must be attached to a main, independent clause. Adverb clauses may come at the beginning or end of a sentence. Look at these examples:
While you were sleeping, I washed the dishes.
I washed the dishes while you were sleeping.
The meanings of both sentences are the same. Note that when the adverb clause comes first, it is followed by a comma. When it comes at the end of the sentence, you do not need a comma.
There are 4 types of adverb clauses: time, contrast, cause and effect, and condition. We will look at each type.
Adverb clauses to time
