A verb appearing as ᴱQ. pukta- in the Qenya Lexicon of the 1910s under the early root ᴱ√PU(HU) “generate” (QL/75). According to the editors, it was written over an erased word whose glosses seems to have been “coire”, which is Latin for “to copulate”; elsewhere derivatives of this root had to do sex and sexual organs.
Neo-Quenya: For purposes of Neo-Quenya I would adapt this word as ᴺQ. puhta- “to copulate, have sex” as suggested by Fiona Jallings, with the later Quenya sound change of kt to ht.
puhta noun "coitus" (PE13:163, gloss specified to refer to "one act"; a more general word for "sex" could perhaps be derived by adding an abstract or generalizing ending like -lë)
