Etymology
From Middle English tuwel, from Old French tueil, tuel, tudel (“tube, pipe”) (whence modern French tuyau), from Vulgar Latin *tūta, from Frankish *thūta (“pipe”), from Proto-Germanic *þeutǭ (“pipe, channel, flow”), from *þeutaną (“to howl, roar, resound”), from Proto-Indo-European *tu-, *tutu- (“bird-cry, shriek”). Compare Spanish and Portuguese tudel, from the same Germanic source.
