1. Complex Sentences

2. Definition
A complex sentence is sentence made by joining an independent clause and a dependent clause.

3. Clauses An independent clause makes sense by itself. Example:
The bell rang for class.

4. Clauses
The dependent clause does NOT make sense by itself. Without the help of an independent clause, it is a fragment.
A dependent clause always begins with a subordinate conjunction
Example:
When the bell rang for class.
