the.com/supply closet

means A small storage room in an office or school where paper, pens, cleaning supplies, and other everyday materials are kept.

from A plain compound of 'supply' (from Latin supplere, 'to fill up, complete') and 'closet' (from Old French clos, 'enclosure,' tracing back to Latin claudere, 'to shut'). Neither word is exotic — closets began as small private chambers for prayer or storage in medieval households, and over centuries the word shrank right along with the rooms it named, until 'closet' meant any small enclosed space. Pair it with 'supply' and you get exactly what it says: a shut-up space for keeping things filled. Its reputation as a hideaway for office gossip and clandestine meetings is pure cultural folklore, not etymology — the walls just happen to be thick and the room is rarely checked.
