elphir

masculine name. Elphir

The 23rd prince of Dol Amroth (PM/223). The language and meaning of this name are not clear, but unlike the names of earlier princes, this name appears to be Sindarin instead of Adûnaic. It may be a combination of the plural e(i)lph of alph “swan” and the noun hîr “lord”, hence: “✱Lord of Swans” (as suggested by David Salo, GS/348).
