A pantry is an area in or near a kitchen where food is stored. When you buy a hundred boxes of macaroni and cheese that are on sale, you'll need to make room in the pantry for them.
Not every kitchen has a pantry, a dedicated space for storing food and other supplies. In some cases a pantry is a closet or cupboard with shelves, and sometimes a pantry is an entirely separate room adjacent to the kitchen. The Anglo-French source of pantry, panetrie, means "bread room," from the Medieval Latin panataria, "room of a servant in charge of food or bread." The Latin root, panis, means "bread."
