urine: [14] Urine comes via Old French urine from Latin ūrīna, which may be related to Greek oúron ‘urine’ (source of English urea [19], ureter [16], urethra [17], and uric [18]) and Sanskrit varsa- ‘rain’. Urinal [13] comes from the late Latin derivative ūrīnālis. [urine etymology, urine origin, 英语词源]
