What is a noun clause?

A noun clause is a type of dependent clause that functions as a noun within a sentence. It acts as the subject, object, or complement of the main clause. A noun clause typically begins with words such as "that," "whether," "if," "who," "whom," "what," "which," "why," or "how."

Noun clauses can serve various functions within a sentence. They can act as the subject of a sentence, taking the place of a noun. For example, in the sentence "What she said is true," the noun clause "What she said" functions as the subject.

Noun clauses can also function as the object of a verb or preposition. For instance, in the sentence "I know that he is coming," the noun clause "that he is coming" acts as the direct object of the verb "know."

Furthermore, noun clauses can serve as the complement of a linking verb, providing additional information about the subject. For example, in the sentence "Her dream is to become a doctor," the noun clause "to become a doctor" functions as the complement of the linking verb "is."

Noun clauses can be introduced by various words or phrases, depending on the specific function they serve in the sentence. For example, if the noun clause functions as the subject, it can be introduced by words like "what," "who," or "whether." If the noun clause functions as the object, it can be introduced by words like "that," "if," or "how."

In summary, a noun clause is a dependent clause that acts as a noun within a sentence, serving as the subject, object, or complement. It is introduced by words or phrases that indicate its function and can provide essential information to the overall meaning of the sentence.
