The 13th king of Arthedain (LotR/1038). The initial element of his name is the prefix ar(a)- “noble” and its final element might be the lenited form val of mal(t) “gold” (as suggested by David Salo, GS/342).
Conceptual Development: In the draft of Appendix A of the Lord of the Rings, his name was first given as Aravallen possible containing mallen “golden”, before it was revised to Araval (PM/209).
ara (prefix “high, noble, royal”) + mall (“golden, of gold”)
