8.3 GRAMMAR: Using Adverb Clauses

<a href=Logo for Open Oregon Educational Resources" />

The last kind of clause that we will study in this course is the adverb clause. Like the adjective clause, the adverb clause is also a great tool for adding specific supporting detail. It allows you to combine short sentences to improve not only the accuracy, but also the rhythm and flow of your writing. More importantly, adverb clauses really help you to demonstrate the relationships among ideas.

A CLOSER LOOK

A clause is a group of words with a subject and a verb.

A clause can be independent. That means it has a subject and a verb, and it expresses a complete idea. A simple sentence is an independent clause.

A clause can be dependent. That means it has a subject and a verb, but it does not express a complete idea. It must be attached to an independent clause to make sense.

An adverb clause is a dependent clause. It works like an adverb. It has a subject and a verb, but it does not express a complete idea.

Adverb clauses tell when something happened, why it happened, in spite of what happened, where it happened, how it happened, or a condition under which it happened.

An adverb clause may come before the main clause, after the main clause or between the subject and verb of the main clause.

The punctuation depends on the position of the adverb clause. When the adverb clause come BEFORE the main clause, a comma is used at the end of the adverb clause. Generally no comma is used when the adverb clause comes AFTER the main clause. When the adverb clause comes WITHIN the main clause (between the subject and verb), two commas are used.

Adverb clauses always begin with a subordinating conjunction. The subordinating conjunction expresses relationships of time, place, condition, contrast, cause, manner, purpose. Some of the subordinating conjunctions, such as as and after, are identical to prepositions. Unlike prepositions, however, they must be followed by complete clauses.

Here are some examples of subordinating conjunctions and their uses:

Type Use Subordinating Conjunctions
Condition to describe what must happen first so that another thing can happen if, even if, unless, when, in case, in the event that, provided that
Reason to describe the cause of an action in the main clause because, since, as, now that, because of
Contrast to describe opposite information to something in the main clause while, although, whereas
Concession to describe unexpected or surprising information relative to the main clause although, though, even though
Result to show what happens after the action of the main clause happens so, so … that (so much that, so many that, so few that, so adjective or adverb that), such (a/an) noun that
Purpose to describe why something happens so, so that
Time to describe when the action of the adverb clause happens in relation to the action of the main clause after, as soon as, before, when, while, until, whenever, as, once, by the time, since
Manner to describe how or in what way something in the main clause happens as, as though, as if

Practice

Now practice with this exercise; it is not graded, and you may repeat it as many times as you wish:

Reducing adverb clauses

You can shorten only time clauses and reason clauses.

You can shorten them only if the subject is the same in both the independent and the dependent clauses.
