what is a dependent and independent clauses
Definition. A dependent clause is a group of words that has both a subject and a verb but (unlike an independent clause) cannot stand alone as a sentence. Also known as a subordinate clause. Dependent clauses include adverb clauses, adjective clauses, and noun clauses. Although exceptions can be found, a dependent clause at the beginning of a sentence is usually followed by a comma (as in this sentence).
An independent clause (a clause is a group of words that contains at least one subject and one verb) is one that can stand on its own two feet--independently. You can join independent clauses if you want to. This is called coordination. A dependent person is one who needs help from another, more independent person.
