Complex Sentences | Definition and Examples

Complex Sentences | Definition and Examples

Complex sentences combine an independent clause (a complete sentence) with one or more dependent clauses (sentence fragments). You can read more about independent and dependent clauses here.

Independent and dependent clauses can be linked using subordinators, which indicate that a dependent clause is beginning. These subordinators include “because,” “since,” “when,” “after,” “if,” and “although.”

In this example, the subordinator “although” demonstrates the connection between the first dependent clause and the independent clause, linking them together.

As you write complex sentences, you’ll need to pay attention to commas.

If the dependent clause is positioned at the beginning of the sentence, as in the example above, you end the dependent clause with a comma.

On the other hand, a dependent clause that appears in the midst of an independent clause should have commas positioned around it.

And if the dependent clause occurs at the end of a sentence, no comma is needed.
