A noun for “glutton” in the Qenya Lexicon of the 1910s derived from the early root ᴱ√LAVA “lick”, with a stem form of láveard- (QL/52).

Neo-Quenya: I think this word can be salvaged for purposes of Neo-Quenya as an atypical agental formation from the later version of the root: √LAB “lick”. If the final r is from the agental suffix ✶-ro however, it probably no longer has a specialized stem form.
