gull: [15] Gull is a Celtic contribution to English. It was probably borrowed from Welsh gwylan, which together with Cornish guilan, Breton gwelan, and Old Irish foilenn, goes back to a prehistoric Old Celtic *voilenno-. (The Old English word for ‘gull’ was mǣw, as in modern English sea mew.) [gull etymology, gull origin, 英语词源]
