probably from the Old English place name Hwæssingatūn (literally "a settlement of the household of Hwæssa"), from Hwæssa (a Saxon chieftain's name) + -ing ("belonging to") + tūn ("homestead, settlement"). It was attested in 1096 as Wasindone. Hwæssa is of uncertain origin, said to possibly correspond to waþ ("hunt") + sige ("victory"), or possibly related to hwæte ("wheat").
