From Ancient Greek λυγκούριον (lunkoúrion). Ancient writers give a derivation from λύγξ (lúnx, “lynx”) + οὖρον (oûron, “urine”), as the stone was said to be the crystallized urine of the lynx, but this is apparently a folk etymology. Judging by its wide variety of forms in Ancient Greek, the word is probably of Pre-Greek origin.
lyncūrium n (genitive lyncūriī または lyncūrī); second declension
