Qenya 

herendil

masculine name. Fortune-friend

Son of Elendil in Tolkien’s unfinished “Lost Road” story from the 1930s (LR/49). The name also appeared in The Etymologies where it was glossed “Eadwine” (Old English for “Fortune-friend”) and given as a compound of heren “fortune” and -(n)dil “friend” (Ety/KHER, NIL). In later versions of the Fall of Númenor, this character’s name was switched for that of his father, so that he became Elendil as he was eventually named in The Lord of the Rings.
