Cabinet or enclosed storage spaces, usually in a kitchen or pantry, used to keep dishes, food, or other items.
Originally from 'cup board'—literally a board or table for holding cups. Over time it became one word 'cupboard' as the meaning shifted to any cabinet for storage rather than just cup display.
The term 'cupboard' perfectly shows how compound words evolve—it started as two literal words describing furniture's function, then merged into one word that came to mean any storage cabinet, even ones that never hold cups.
