O.E. wæstling "sheet, blanket;" Hittite washshush "garments," washanzi "they dress"). The Gmc. forms "were homonyms of the vb. for 'prevent, ward off, protect' (Goth. warjan, O.E. werian, etc.), and this was prob. a factor in their early displacement in most of the Gmc. languages" [Buck]. Shifted from a weak verb (past tense and pp. wered) to a strong one (past tense wore, p.p. worn) in 14c. on analogy of rhyming strong verbs such as
bear and
tear. Secondary sense of "use up, gradually damage" (c.1275) is from effect of continued use on clothes. To be the worse for wear is attested from 1782; wear and tear is first recorded 1666.
