dor haeron

proper name. Dor Haeron

Name of the region between the Isen and the Entwash, attested only in drafts of the Lord of the Rings appendices (PM/273). The initial element is clearly dôr “land”, and the final element may be a variation of hae “very far away” or haer “remote”, hence: “✱Distant Land” (as suggested by David Salo, GS/374).
