How can you identify a noun clause in a sentence?

A noun clause is a group of words that functions as a noun within a sentence. To identify a noun clause in a sentence, look for a group of words that:

1. Functions as the subject, object, or complement of a verb
2. Begins with a subordinating conjunction (such as that, whether, if, etc.)
3. Answers the question "what?" or "whom?" within the sentence

For example, in the sentence "I heard that she is moving to a new city," the noun clause is "that she is moving to a new city" because it functions as the object of the verb "heard" and begins with the subordinating conjunction "that."
