dish

Dish comes from Middle English dissh/disch, from Old English disċ ("plate; bowl; dish"), which traces back through Proto-West Germanic *disk ("table; dish") to Latin discus.

The word started out covering both furniture and tableware at once — a flat surface for setting food on — before English narrowed it down to just the vessel, and later let it stretch to mean the food served in it.

It's a doublet of desk, disc, disk, dais, discus, and diskos — all descendants of the same Latin discus, just borrowed into English at different times and in different shapes. It's also cognate with German Tisch and Dutch dis, both meaning "table," which shows how close the vessel-versus-surface meanings once sat together.
