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.

muku

root. cacare [Latin], *defecate

The root ᴱ√MUKU “cacare [Latin = defecate]” appeared in the Qenya Lexicon of the 1910s with derivatives like ᴱQ. múko “dung” and ᴱQ. muqa “filthy” (QL/63). As there are no other roots of similar meaning in Tolkien’s later writing, I think it is worth retaining a Neo-Eldarin root ᴺ√MUK for this purpose.

muku Speculative

root. *silent

A hypothetical early root based on words like G. mug- “keep silent, say nothing (about)” and G. maug “silent” (GL/57-58). In later writings Tolkien used words like S. dîn for “silence” in Sindarin.
