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.
nut-
verb. to tie
ferna
noun. mast, beechnuts
A word in The Etymologies of the 1930s glossed “mast, beechnuts” under the root ᴹ√PHER(EN) “beech” (Ety/BERETH). Most likely the gloss “mast” refers to the fallen nuts or acorns used in ancient times to feed pigs, which was one of the senses of the Old English word “mæst”. The mast of a ship would instead be tyulma (PE21/80; Ety/TYUL).
