The word ᴱQ. sornion “eyrie” appeared in the Qenya Lexicon of the 1910s as an elaboration of ᴱQ. sor(ne) “eagle” (QL/86). The word also appeared in the contemporaneous Poetic and Mythological Words of Eldarissa (PME/86).
Neo-Quenya: Since Q. soron, sorno or sorne were words for “eagle” in Tolkien’s later writings, I think ᴺQ. sornion “eyrie” can be retained for purposes of Neo-Quenya, perhaps originally a genitive plural “of the eagles”.
A word glossed “ocean” in notes associated with drafts of the Oilima Markirya from around 1930 (PE16/77). This word did not appear in the final version of the poem. Its etymology is unclear, but Gilson, Welden and Hostetter suggest it might be connected to ᴱQ. laiqa “green”, a colour used to describe the ocean in some drafts of the poem (PE16/78).
