Question

Which word in the sentence is a noun? The music they’re playing is loud. A. they’re B. playing C. loud D. music

Answer 1

A "They're" is "they are" which is a clause-- nowhere near a noun.

B "Playing" is a verb.

C "Loud" describes a noun, music, so it is an adjective.

D "Music" is a noun because it falls in the category of "idea, place, thing".
