The 30th king of Gondor (LotR/1050) and also the name of the younger brother of Rómendacil II (LotR/1037). This name might break down as cala “light” and mehtar “warrior” (a possible late variant of ᴹQ. mahtar; see QQ/mehtar), but I think it could also be a compound of calima “bright” and ohtar “warrior”, though why [a+o] became [e] is unclear.
