undómiel

feminine name. Evenstar

A sobriquet of Arwen translated “Evenstar” (LotR/227, RC/757), a compound of undómë “twilight” and archaic †él “star”. The second element could also be interpreted as -iel “daughter”, giving this name the same meaning of that of her ancestress Tinúviel (Sindarin for “Daugher of Twilight”), whom Arwen was said to resemble (LotR/227).
