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.

adjective. sunburnt, swart, dark-brown

amrog-dorn

noun. brown wanderer, gipsy

A word glossed “brown wanderer, gipsy” in the Gnomish Lexicon of the 1910s, a combination of G. amrog “wanderer” and the mutated form of G. torn “swart, dark-brown”, with a plural form amruith-torni (GL/19). It is not clear how plural amruith relates to singular amrog, but it might contain a variant form of G. gwaith “people” (GL/44): amr + gw(a)ith > amrwith > amruith.
