Complex Sentence

Definition Of Complex Sentence :

A complex sentence is a sentence with an independent clause and at least one dependent clause. The dependent clause is introduced by either a subordinate conjunction (such as although, while, or because) or a relative pronoun (such as who or which). A complex sentence is very different from a simple sentence or a compound sentence because it makes clear which ideas are most important.

Example Of Complex Sentence :

1. Although Tom reads novels, Jack reads comics.
2. When he was younger, Mike had many dogs.
