The 8th and 12th kings of Arthedain (LotR/1038). The initial element of this name is the prefix ar(a)- “noble” and its final element is probably the lenited form veleg of beleg “great, mighty”.

Conceptual Development: In the draft of Appendix A of the Lord of the Rings, the name of Arveleg I was first given as Beleg, and the name of Arveleg II was first given as Argeleb (PM/209).
