Leader of the House of Hador, one of the three tribes of the Edain (S/147). In a geneology from 1959, the name seems to be translated “Warrior” in Hador Lorindol “the Warrior Goldenhead”, appearing beneath S. Magor “the Sword” and S. Hathol “the Axe” (WJ/234).
Conceptual Development: In Silmarillion drafts from the 1930s, this name appeared as N. Hádor and Hador with both long and short a (LR/146). In The Etymologies of the 1930s, N. hador was translated as “thrower” (Ety/KHAT).
