INDEPENDENT CLAUSE

Independent clauses are those that can stand on their own. Whereas, dependent clauses can not. 

Dependent clauses are used to  make independent clauses more interesting or complete. There must be an independent clause for a dependent clause to be present. 

I need to identify independent clause to properly define the use of dependent clause.

An independent clause has three components: subject, an action or predicate, express complete thought. An independent clause can simply be a subject and a verb. Ex: She sleeps.

A dependent clause has a subject and verb but does not express a complete thought. Its presence in a sentence is made known when it is preceded by a marker word or conjunction.
