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.

lak-

neuma

noun. snare, snare, *noose

A noun in The Etymologies of the 1930s glossed “snare” under the root ᴹ√SNEW “entangle” (Ety/SNEW).

Neo-Quenya: Its Noldorin cognate was also glossed “noose”, so that meaning might apply to neuma as well; this would help distinguish it from later remma “snare” which had more to do with nets.
