A word appearing as ᴱQ. liantasse “vine” in the Qenya Lexicon of the 1910s, an elaboration of ᴱQ. liante “tendril” under the early root ᴱ√LI+ya “unite many as one” (QL/53).

Neo-Quenya: The later root ᴹ√SLIG was the basis for words like ᴹQ. liante “spider” and ᴹQ. lia “fine thread, spider filament”, so I think ᴺQ. liantassë “vine” can be salvaged as a derivative of this root, perhaps originally meaning “*an entwining”. This word was used for “vine” in Helge Fauskanger’s Neo-Quenya New Testament (NQNT).
