A word appearing as ᴱN. huigion or hygion “fututor” (= Latin “one who copulates”) in Early Noldorin Word-lists of the 1920s (PE13/163), an agental form of ᴱN. hug- “futuere” (= Latin “copulate”).

Neo-Sindarin: For purposes of Neo-Sindarin, I would adapt this word as ᴺS. pogron “one who copulates” based on the updated form of the verb: ᴺS. pog- “to copulate, have sex”.
