Words like because, as if, and although introduce noun clauses. true or false

False

Explanation:

A noun clause is a dependent clause (a group of words containing a subject and a verb and that can not stand on its own) that acts as a noun in a sentence, and they tend to start with how, that, what, whatever, when, where, whether, which, whichever, who, whoever, whom, whomever, and why. Words like "because", "as if", and "although" do not introduce these type of clauses.

Examples of sentences with noun clauses are the following (noun clauses underlined):

Whoever wants cake should ask me for a piece of it.

Tomorrow, you can do whatever you want.

I don't understand why you came.
