A verb appearing as ᴱQ. tyuru- in the Qenya Lexicon of the 1910s with the gloss “to ‘turn’ milk, curdle (blood etc.)” derived from the early root ᴱ√TYURU “curdle” (QL/50). The form Q. tyuru- is also mentioned in the contemporaneous Gnomish Lexicon of the 1910s as related to G. cûr “cheese”, but it isn’t clear whether this is a reference to the verb or the root (GL/28).
Neo-Quenya: I’d retain ᴺQ. tyur- “curdle” for purposes of Neo-Quenya, derived from a Neo-Root ᴺ√KYUR.
A word appearing as ᴱQ. ilin (ilim-) “milk” in the Qenya Lexicon and Poetic and Mythological Words of Eldarissa of the 1910s derived from the early root ᴱ√ILI “shine oily” (QL/42; PME/42).
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.
