I recently learned that "à boire" can be used as an abbreviation for "quelque chose à boire". As in: "Je veux à boire".
This got me wondering: if I see "Je + [conjugated verb] + à boire", will "à boire" always stand for this abbreviation?
I looked at this website (https://www.thoughtco.com/a-french-preposition-1368910). It says:
avoir à + infinitive = to be obliged to [infinitive]
Is "J'ai à boire." ambiguous? That is, could it mean "I have something to drink", as well as "I am obliged to drink"?
