Keep Calm and Use Complex Sentences

Definition

In grammar, a complex sentence is a sentence with one independent clause and at least one dependent clause. A complex sentence is often used to make clear which ideas are most important, and which ideas are subordinate.


Complex Sentence Examples

“I ate the meal that you cooked.” In this example, “I ate the meal” is an independent clause, while “that you cooked” is a relative clause. The independent clause could stand alone as a simple sentence without the relative clause.

“I enjoyed the apple pie that you bought for me.” Here, “I enjoyed the apple pie” is an independent clause and “that you bought for me” is a relative clause.

“I ate breakfast before I went to work.” This has “I ate breakfast” as an independent clause, and “before I went to work” as a dependent clause.
