Neo-Quenya: Qenya “oil” words were derived from other primitive forms in the 1920s (ᴱ✶mḷgo: PE13/139), but I prefer to retain ᴺQ. ilin “milk” for purposes of Neo-Quenya, derived from an Neo-Root ᴺ√ILIM.
A word appearing as ᴱQ. ilimba “milky” in the Qenya Lexicon of the 1910s, an adjectival form of ᴱQ. ilin (ilim-) “milk” (QL/42).
Neo-Quenya: I retain ᴺQ. ilimba “milky” for purposes of Neo-Quenya as the adjectival form of ᴺQ. ilin “milk”.
