Second child and only daughter of Elros, known only from a genealogy chart on UT/210. Her name is a compound of tindómë “twilight” and -iel “daughter; feminine suffix”, so perhaps means “*Daughter of Twilight”. This is the same meaning as S. Tinúviel, but Tinúviel’s Quenya name was Tindómerel, with its final element derived from seldë “daughter”.
