Noun Clause. A noun clause is any clause that replaces, and functions as, a noun. It's another type of dependent clause. 1  For example, in the sentence, 'You really do not want to know the ingredients in Aunt Nancy's stew,' the noun is ingredients.n independent clause, also called a main clause, is a clause that can stand on its own. It contains all the information necessary to be a complete sentence. An independent clause has a subject that tells you what the sentence is about and a verb that tells you what the subject is doing.
