Etymology

From Middle English fetten, feten, from Old English fetian, fatian (“to bring, fetch”), probably a conflation of Proto-West Germanic *fetan, from Proto-Germanic *fetaną (“to go”), from Proto-Indo-European *ped- (“to walk, stumble, fall”); and Proto-West Germanic *fatōn, from Proto-Germanic *fatōną (“to hold, seize”), also from Proto-Indo-European *ped-. Cognate with Dutch vatten (“to catch, grab”), German fassen (“to lay hold of, seize, take, hold”). Compare also Icelandic feta (“to find one's way”). More at fetch.
