Elf-fathers

From Tolkien Gateway

Elf-fathers were the three male Elves who awoke at Cuiviénen and then formed the Three Clans. Imin, Tata, and Enel were their names which translate to "One", "Two", and "Three" respectively. Their followers were thus named Minyar (Firsts), Tatyar (Seconds), and Nelyar (Thirds).
