There are two ways to fix a dependent clause. You can remove the subordinating conjunction (although, because, if, when). Often just removing that word will reveal an independent clause.
Another option is to attach the dependent clause to an independent clause. A dependent clause needs an independent clause in order for the sentence to make sense. In the following examples, the dependent clause precedes the independent clause. Notice that the dependent clause does not make sense as its own sentence. When the dependent clause joins an independent clause, the entire sentence makes sense.
Punctuating Dependent Clauses
Did you notice the punctuation in the examples? If a dependent clause appears before the independent clause in the sentence, add a comma to separate the two clauses. If the dependent clause appears after the dependent clause, no comma is needed.
