anything edible; food
Latin com- + -edere 'to eat'
1837, "article of food," from French comestible (14c.), from Late Latin comestibilis, from Latin comestus, past participle of comedere "eat up, consume," from com- "thoroughly" (see com-) + edere "to eat" (see edible). It was attested earlier as an adjective (late 15c.) meaning "fit to eat" but seems to have fallen from use 17c., and the word was reintroduced from French.
