Answer:
<u>leaves a thought unfinished</u>
Explanation:
As opposed to an independent or main clause, a dependent clause is a group of words having a subject and a verb that does not express a complete thought. It is a construction that can not stand alone because it would leave a thought unfinished. Here are some examples of sentences containing dependent clauses (underlined):
<em><u>If she hadn't had that accident</u></em><em>, she wouldn't have stayed here.</em>
<em>Maria, </em><em><u>who is my oldest sister,</u></em><em> has been ill for so many years.</em>
<em>I admire him </em><em><u>although I don't agree with his point of view.</u></em>
