After the game, we got something to eat. Are the phrases after the game and to eat? And if yes, are they both adverb phrases?

3 answers

to eat = an infinitive (a verb form)

After the game - yes, it's adverbial.
so to eat is not an adjective or an adverb phrase right?
right

Infinitives can be parts of phrases, but they themselves are not phrases.
