A title of Oromë as the Lord of Forests (S/29). The name is genitive plural of alda “tree”, so its literal meaning is “Of Trees”.
Conceptual Development: This name was well established in Tolkien’s lengendarium, appearing as ᴱQ. Aldaron “King of Forests” in the earliest Lost Tales (LT1/66) and in later stories as ᴹQ. Aldaron “Lord of Forests” (SM/79, LR/206), always having the same basic meaning and form. This name appeared in the published version of The Silmarillion, but according to Christopher Tolkien, his father deleted this name from the final version of the “Valaquenta”, leaving only S. Tauron (MR/202, notes §8). A shorter form Aldar appeared in linguistic notes from the 1950s (PE22/86), though whether this form was intended to be a name of Oromë is unclear.
