Meaning

noun a small high-pitched flute similar to a piccolo; has a shrill tone and is used chiefly to accompany drums in a marching band

originBorrowed from Scottish Gaelic Fìobha, said to date back to the eponym Fib, one of the seven sons of the legendary Pictish king Cruithne. Possibly related to the Uip attested in the Pictish kings lists, in turn possibly related to the Latin Vepogenus, in which the first element is the Proto-Brythonic predecessor of Welsh gwep (“face”).
