A noun appearing as ᴱN. hoith “coitus” (a single act of sex) in Early Noldorin Word-lists of the 1920s, cognate to ᴱQ. pukta or puhta (PE13/147, 163), where the initial p became h as was often the case in the Early Noldorin of the 1920s.
Neo-Sindarin: Fiona Jallings adapted this word as ᴺS. puith “coitus, ✱sex” for purposes of Neo-Sindarin to better fit Sindarin phonetic developments.
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)
