A commode is any of several pieces of furniture. The word commode comes from the French word for “convenient” or “suitable”, which in turn comes from the Latin adjective commodus, with similar meanings.

n the English-speaking world, commode passed into cabinet-makers' parlance in London by the mid-eighteenth century, to describe chests of drawers with gracefully curved fronts, and sometimes with shaped sides as well, perceived as being in the “French” taste. (source)
