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.

A word appearing as G. bart “change” in the Gnomish Lexicon of the 1910s (GL/22), clearly based on the early root ᴱ√vṛt (QL/102).

elt

noun. change

A word given as G. elt “a change” in the Gnomish Lexicon of the 1910s, originally given as elt “a dig, a poke (probe), a tug, lug” (GL/32). I suspect the original gloss was based on the early root ᴱ√ELE “drive, push, thrust, send forth” (QL/35).
