The word "kidney" likely originated from Middle English kidenere, but its deeper roots are unclear. The first element kid- may relate to Old English cwið (womb) or Norse kviðr (belly), suggesting an early association with internal organs. The suffix -ney was a diminutive, now obsolete. Over time, the term specialized to refer specifically to the renal organs, shedding its earlier broader meanings.
