A word appearing as ᴱQ. tūvima “acceptable” in the Qenya Lexicon of the 1910s based in the verb ᴱQ. tuvu- “receive, accept” (QL/96).
Neo-Quenya: For purposes of Neo-Quenya I would update this adjective to ᴺQ. cávima “acceptable” based on the later verb cav- “receive, ✱accept”, especially since túvima was glossed “discoverable” in Tolkien’s later writings (PE22/155). In his NQNT (NQNT) Helge Fauskanger instead had ᴺQ. maicámima “acceptable” (lit. “well-receivable”) based on the alternate verb form cam- “receive”.
A word appearing as ᴱQ. natto “thing, affair” in the Qenya Lexicon of the 1910s, an elaboration of ᴱQ. nat “thing” under the early root ᴱ√NĀ “be, exist” (QL/64). The word reappeared with the glosses “affair, matter, thing” in the English-Qenya Dictionary of the 1920s with a plural nattur indicating a stem form of nattu-, but this entry was deleted (PE15/68).
Neo-Quenya: I’d retain ᴺQ. natto (nattu-) for purposes of Neo-Quenya since both Q. nat “thing” and √NĀ survive in Tolkien’s latter writings, but I would limit its sense to “affair, matter” as in “✱a thing that is happening/has happened”.
