Which kind of clause functions as a subject object or complement?

The kind of clause that functions as a subject, object, or complement is called a noun clause.

Here's a breakdown:

* Noun clauses act like nouns in a sentence. They can be the subject, the direct object, the indirect object, the object of a preposition, or the complement of a verb.

* Subject: *What they said* surprised everyone.

* Direct object: I know *who stole the cookies*.

* Indirect object: She told *whoever was listening* the truth.

* Object of a preposition: We talked about *what happened at the party*.

* Complement: The problem is *that we are out of time*.

Key characteristics of noun clauses:

* They typically start with words like: *that, what, who, whom, whoever, whomever, whichever, whatever, whether, if, how, why, when, where*.

* They have a subject and a verb.
