the word 'spigot' entered english in the 14th century from the old french 'espigot', a term of obscure lineage. one plausible theory traces it to vulgar latin, connecting it to 'spica', meaning an ear of grain or a spike, which metaphorically described a pointed peg used to stop a hole. this literal sense of a simple stopper or plug evolved over centuries into the modern meaning of a valve or tap that controls the flow of liquid from a barrel or pipe. the semantic journey reflects a shift from a simple, solid object that blocks an opening to a more complex mechanical device that regulates flow.

this word is a simplex form. it is a loanword from old french 'espigot', of uncertain origin, possibly from a diminutive form of a vulgar latin root related to 'spica' (ear of grain, spike), suggesting a pointed peg or stopper.
