Word Origin & History
c.1400, from O.Fr. fausset "stopper," perhaps dim. of L. faux, fauc- "throat." Spigot and faucet was the name of an old type of tap for a barrel or cask, consisting of a hollow, tapering tube, which was driven at the narrow end into a barrel, and a screw into the tube which regulated the flow of the
liquid. Properly, it seems, the spigot was the tube, the faucet the screw, but the senses have merged or reversed over time. Faucet is now the common word in Amer.Eng. for the whole apparatus.
