A word appearing as ᴱQ. melpo “gooseberry” in the Qenya Lexicon of the 1910s, which Tolkien further described as “a fruit of the gooseberry type — squashy, with seeds” (QL/61). Its etymology is unclear, but it might be a combination of ᴱ√MELE “love” and a reduced form of ᴱQ. pio “berry”.

Neo-Quenya: Since there are no later options for this word, I’d retain ᴺQ. melpo “gooseberry” for purposes of Neo-Quenya.
