I have many people who read my blog asking me WTF is faucet.. lol.. I am not complaining. Let me explain.
Faucet is any device for controlling the flow of liquid from a pipe or the like by opening or closing an orifice. In other words its a tap.
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.
Spigot is a common variant for faucet and is widely used in the Midland U.S. Elsewhere, faucet is more commonly used, esp. in the Northern U.S. In India, I am not sure if the term faucets is used.
