means A small, fast-evaporating organic molecule (the simplest ketone) used as a solvent for dissolving fats, resins, and plastics — and the stuff that makes nail-polish remover reek.

from From 'acetic' (vinegar-related) plus the chemical suffix '-one', which chemists use to mark ketones. 'Acetic' itself traces back to Latin 'acetum', meaning vinegar — because acetone was first isolated from the dry distillation of acetates, salts derived from vinegar's acetic acid. So the name is basically a chemist's receipt: start with vinegar salts, heat them, and out comes a new compound that still carries vinegar's name in its DNA, even though it smells nothing like salad dressing.
