proper name. Erchirion

The 2nd son of Imrahil, appearing only in a genealogy chart of the house of Dol Amroth (PM/221). His name may be a combination of er “one”, a mutated form chir of hîr “lord” and the patronymic suffix -ion “son”, though David Salo suggested the initial element may be a variant form of the prefix ar(a)- “noble” (GS/348).


er“one, alone”
hîr“lord, master”
