A word appearing as ᴱQ. ilqa “oily, smooth, glossy” in the Qenya Lexicon of the 1910s under the early root ᴱ√ILI “shine oily” (QL/42).
Neo-Quenya: For purposes of Neo-Quenya I would update this word to ᴺQ. milla “oily” from ✱mil’gā for better compatibility with ᴺQ. millo “oil”.
ilqua ("ilqa")noun "everything" (IL, VT45:24), "all" (FS); ilquainen ("ilqainen") a word occurring in Fíriel's Song, translated "to all". It would appear to be ilqua "all" with a dative pl. ending. However, in Tolkien's later Quenya -inen is the ending for instrumental pl. (FS)
