A noun appearing as ᴱQ. puntl in the Qenya Lexicon of the 1910s under the early root ᴱ√PU(HU) “generate”, with an erased gloss “mem. vir.” (QL/75). As suggested by the editors, “mem. vir.” is an abbreviation of Latin “membrum virile” = “male organ”, hence “*penis”.

Neo-Quenya: I would adapt this word as ᴺQ. puncil “male organ, *penis” based on a Neo-Root ᴺ√PUK.
