Dependent Words

Another way to test for fragments is to ask the question:  Are statements with dependent words connected to complete sentences (independent clauses)?  Dependent clauses have subject and verbs, but they begin with subordinating conjunctions (such as if, because, or when) or relative pronouns (such as who, which, or that). 
Because her opposition to the city dump is well known.
That you drove this morning.
Dependent-word statements can be corrected by connecting them to complete sentences or rewriting them.
(Attached to a sentence):        Because her opposition to the city dump is well
known, she is respected by those in the environmental movement.
(Correct):                                 Her opposition to the city dump has made her respected in the environmental movement.
(Attached to a sentence):       Raju has an antique car that you drove this morning.
 (Correct):                                You drove Raju’ antique car this morning.
In order for you to recognize dependent words, a list of the common words is given below.
