A larder is etymologically a "bacon room" — and a pantry is a "bread room" — medieval households named their storage rooms after the specific foods kept inside.
A cool room or cupboard used for storing food, especially before the widespread use of refrigeration.
From Anglo-Norman larder, from Old French lardier (a place for storing bacon/lard), from Medieval Latin lardārium (a store for bacon), from Latin lārdum or lāridum (bacon fat, lard), possibly from Greek lārinos (fattened, fat). Key roots: lārdum (Latin: "bacon fat, lard").
The larder is etymologically a bacon room — from Latin lārdum (bacon fat, lard). In medieval households, the larder was one of several specialized storage rooms: the pantry stored bread (from French pain, bread), the buttery stored wine and ale (from French bouteille, bottle), and the larder stored meat and animal fats. Each room's name preserves the specific food it housed
