Complex sentences express a single idea and a supporting idea. The structure of a complex sentence contains a main clause and a subordinate clause that supplies additional information to the main clause. Complex sentences are simply sentences with a main idea and a supporting idea that further explains the main idea or clarifies it. Dependent clauses in a complex sentence could provide circumstantial information about the main idea and proposition. Complex sentences are mostly introduced by subordinating conjunctions or adverbs where the subordinate clause is separated from the main clause by a comma.

N:B: Subordinate adverbs and conjunctions have been emboldened in the examples.

Examples of a Complex Sentence

b. They are wise even though they don't look like it.
