Writing an effective sentence In order to write an effective sentence, you must be able to recognize and combine dependent and independent clauses to express complete ideas. An independent clause is a group of words that has a subject and a verb and expresses an idea completely. An independent clause is a complete sentence. This is an example of an independent clause: The dog chewed on its bone. The subject of this sentence is “the dog”, and the verb is “chewed”. This sentence completely expresses the idea of what the dog did – it chewed on its bone. A dependent clause is a group of words that contains a subject and a verb but doesn’t express an idea completely. A dependent clause is not a complete sentence. This is an example of a dependent clause: While the dog chewed on its bone … This group of words has the same subject and verb as before, but it doesn’t give the reader the whole picture. It leaves questions – like what was the dog doing while it chewed on its bone? Identifying dependent clauses Dependent clauses usually begin with key words like because, before, while, when, if, so, and in order to, to name a few. If you use one of these words to begin a sentence, you must finish the thought by expressing the idea completely. An effective sentence combines dependent and independent clauses to express a complete idea Many students make sentence errors because they do not complete their thought. The easiest way to create effective sentences that express complete ideas is to combine dependent and independent clauses. This is an example of a combined sentence: While the dog chewed on its bone, it growled at me, so I left it alone. Notice that this sentence has two dependent clauses (“while the dog chewed on its bone” and “so I left it alone”) and one independent clause (“it growled at me”). Together they express a complete thought and provide detail to the reader.
