There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

Early Quenya

liantasse

noun. vine

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 NQNT (NQNT).
