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.
In linguistic analysis, a phrase is a group of words (or possibly a single word) that functions as a constituent in the syntax of a sentence âa single unit within a grammatical hierarchy. A phrase appears within a clause, although it is also possible for a phrase to be a clause or to contain a clause within it.heorists of syntax differ in exactly what they regard as a phrase; however, it is usually required to be a constituent of a sentence, in that it must include all the dependents of the units that it contains.
