cibus

Cibus, cibi, m., second declension: food in general, anything eaten. It sits between panis, which is specifically bread, and victus, which is the whole business of keeping a person supplied. Plural cibi means dishes or kinds of food rather than several meals.

The verb is cibo, cibare, "to feed", and the adjective cibarius means "to do with food" and then, of bread, "coarse, common" - the ration loaf. That is why the word is everywhere in monastic rules, where what the brothers eat and when is a matter of legislation rather than appetite. English took nothing directly, though ciborium, the vessel holding the consecrated bread, arrives through Latin from Greek and has been pulled towards cibus by sense.
