Chwibanogl a chod (f)
From a poem by Iolo Goch (ca. 1320-ca. 1398), published in Charles Ashton, »Gweithiau Iolo Goch« [The works of Iolo Goch] (1895); Its plural form is Chwibenygl (sometimes spelt Chwibenigl [➺ Peate] or even Chwibienygl) a chod; Several variant spellings exist, however, such as Chwibanog, Chwibanogyl, and Chwibonogyl, all of which can mean flute, (musical) pipe, fife, flageolet, or whistle; I was informed that "chod" is a mutated form of the Welsh word "cod", meaning "bag".
