The first draft of the 11th phrase of the Lament of Akallabêth (SD/312). It resembles the final version, but is missing the adverb tâidô and has the verb khay- “to lie” instead of yad- “to go”.
The first two words adūn “west” and batān “road” are the same as in the final version. The verb form akhaini “lay” seems to be the draft-perfect tense of the verb #khay- “to lie”. The word ezendi “straight” (instead of later izindi) appears at the end, perhaps functioning as an adverb.
A noun meaning “west(ward)” (SD/435, PE17/18). Tolkien stated that was “a loan word from Eldarin speech in the language of the Folk of Hador, from which Númenórean was later derived” (PE17/18). Probably it is derived from S. dûn “west”, as suggested by several authors (AAD/9, EotAL/NDU). Tolkien stated that it was an adjective and its proper noun form was adûni (SD/435), but adûn was used as a noun in phrases such as Bârîm an-adûn “Lords of the West” (SD/247).
