fetch: [OE] Fetch comes from the Old English verb fetian ‘go and get’, which survived dialectally as fet well into the 19th century. In the late Old English period a variant feccan developed, from which we get the modern English verb’s /ch/ ending. Its ultimate origin has been disputed. Perhaps the likeliest explanation is that it comes from a prehistoric Germanic *fat- ‘hold’ (source also of Old English fetel ‘girdle, strap’, from which modern English gets fettle).
