Etymology
From Middle English kedney, kydeney, from earlier kidnēre, kidenēre (“kidney”), of obscure origin and formation. Probably a compound consisting of Middle English *kid, *quid (“belly, womb”), from Old English cwiþ, cwiþa (“belly, womb, stomach”) + Middle English nēre (“kidney”), from Old English *nēora (“kidney”), from Proto-West Germanic *neurō, from Proto-Germanic *neurô (“kidney”), from Proto-Indo-European *negʷʰr- (“kidney”). If so, then related to dialectal English near (“kidney”), Scots nere, neir (“kidney”), Saterland Frisian Njuure (“kidney”), Dutch nier (“kidney”), German Niere (“kidney”), Danish nyre (“kidney”), Norwegian nyre (“kidney”), Swedish njure (“kidney”), Ancient Greek νεφρός (nephrós). Alternate etymology traces the first element to Old English *cydde (“sack, belly, scrotum”), from Proto-Germanic *kuddijā (“sack”) as the terms for testicle and kidney were often interchangeable in Germanic (compare Old High German nioro (“kidney", also "testicle”), Old Swedish vig-niauri (“testicle”)).
