Etymologically, the entry records: 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 Eng… Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is kidney, spelled K-I-D-N-E-Y, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.

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”)).
