feast:The notion of ‘eating’ is a secondary semantic development for feast, whose underlying meaning (as may be guessed from the related festival and festivity) has more to do with joyousness than with the appeasement of hunger.
Its ultimate source is the Latin adjective festus, which meant ‘joyful, merry’. This was used as a plural noun, festa, meaning ‘celebratory ceremonies, particularly of a religious nature’, which came down to Old French as feste.
