Answer:
Interjection
Explanation:
Well, if it's an interruption, it would be an interjection, i'd still give the best guess to be interjection, since verbs are used to describe things and a noun is a person, place, or thing, a preposition is in relation to antoher thing ie "I USE this" adjective is used to describe nouns and adverbs are used to modify the meaning of a phrase.
