Is whose a noun clause?

"Whose" is not a noun clause. It's a pronoun, specifically a possessive pronoun.

Here's why:

* Noun clauses function as nouns in a sentence. They answer questions like "who?", "what?", or "where?". For example:

* "Who is coming to the party?" (Noun clause as subject)

* "I know what you did last summer." (Noun clause as object)

* "Whose" acts as a possessive adjective and modifies a noun. It indicates possession or ownership. For example:

* "Whose book is this?"

* "I know the woman whose dog is missing."
