web: [OE] A web is etymologically something ‘woven’. In common with Dutch web, Swedish väf, and Danish voev, the word goes back to a prehistoric Germanic *wabjam. This was derived from the base *wab-, *web-, which also produced English weave ‘make cloth’. The derivative webster [OE] originally denoted a ‘female weaver’, but it now survives only as a surname.
