later and then are what part of speech

Later is used as either an adverb or an adjective. Then is almost always used as an adverb.
Remember that adjectives modify nouns and pronouns; they tell which, what kind of, or how many.
Adverbs modify verbs, adjectives, and other adverbs; they tell when, where, how, and to what extent.
