Beleg (King of Arthedain)
His name means "great' or "large", which may be a reference to his stature (although he may simply be named after the famous Elf of the First Age who shared this name, Beleg Strongbow).
The northernmost and longest lasting of the successor-realms of Arnor after it was divided into three kingdoms (LotR/1039). Tolkien did not translate the name, but as suggested by Hammond and Scull, it might mean “Realm of the Edain” (RC/690). If so, its initial element may be a form of arthor “realm” also seen in the ancient name of Arnor, Arthor na Forlonnas “Realm of the North-harbourage” (PE17/28). The second element is almost certainly the plural Edain “(High) Men” of the noun Adan.
