From Middle English verel, virel, virole (“ferrule; metal pivot on the end of an axle”),[1] altered under the influence of Latin ferrum (“iron”), from Old French virole (“ferrule”), from Latin viriola (“little bracelet”), diminutive of viria (“bracelet worn by men”), from Gaulish, from Proto-Celtic *wēros (“crooked”) (compare Middle Irish fiar (“bent, crooked”), Welsh gŵyr, Breton gwar (“curved”)), from Proto-Indo-European *weyh₁ros (“threaded, turned, twisted”), from *weyh₁- (“to turn, twist, weave”).
