A piece of furniture with shelves and doors used for storing dishes, food, or other items.

Cupboard is formed from "cup" (from Old French *coupe*, meaning a vessel or container) and "board" (from Old English *bord*, meaning a flat surface or table). The word originally referred to a board or shelf for holding cups or dishes.
Think of a 'vessel' ('cup') placed on a 'flat surface' ('board') — that's how you remember that a cupboard is a place for storing dishes or cups.
