Definitions. A clause is a group of words containing a subject and verb. An independent clause is a simple sentence. It can stand on its own. Examples: She is hungry. I am feeling well today. A dependent clause cannot stand on its own. It needs an independent clause to complete a sentence. Dependent clauses often begin with such words as although, since, if, when, and because.
The Grammar Rules for Clauses in English. 1. A clause is a group of words that contains both a subject and a predicate but cannot always be considered as a full grammatical sentence. Clauses can be either independent clauses (also called main clauses) or dependent clauses (also called subordinate clauses). 2. An independent clause (or main clause) contains both a subject and predicate, can stand alone as a sentence (a simple sentence), or be a part of a multi-clause sentence.
