The 14th chieftain of the Dúnedain, grandfather of Aragorn (LotR/1038). The initial element of his name is the prefix ar(a)- “noble” and its final element might be -dor “lord”.

Conceptual Development: In the draft of Appendix A of the Lord of the Rings, his name was first given as Arv[or]eg (4th and 5th letters unclear), revised to Arador (PM/211).
