From Middle English uryne, from Latin ūrīna (“urine”), from Proto-Indo-European *uh₁r-, zero grade of *woh₁-r̥ (“water, liquid, milk”). Related to *h₁ówHdʰr̥ (“udder”) (see udder). Cognate with Old English ūriġ (“wet, moist”). Displaced native English land (“urine”) (from Middle English land, from Old English hland (“urine”)), though lant survives with a specialized sense.
