The 13th phrase of the Lament of Akallabêth (SD/247). The first word êphalak “far away” is an adverb or emphatic adjective; see the entry for -ak for further discussion. The second word îdô “now” is an adverb. The last word Yôzâyan “Land of Gift” is one of the names for Númenor. There is no subjective noun or a verb, so this phrase is a fragment rather than a full sentence.
The typescript version (and all earlier versions) had īdōn “now (is)” instead of īdō “now”. See the entry for îdô for further discussion.
