Question

the movie to see is the one with every actor you love. subject adjective adverb

Explanation:

To determine the part of speech for "to see" in the sentence "The movie to see is the one with every actor you love", we analyze its function. "To see" is an infinitive phrase acting as an adjective (a participial phrase or infinitive as an adjective) that modifies "movie", describing which movie (the one to see). A subject would be a noun/pronoun doing the action, and an adverb modifies a verb, adjective, or other adverb, which "to see" does not do here. So it functions as an adjective - related (infinitive as adjective) element.

Answer:

adjective
