Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
A word appearing as ᴱQ. múko “dung, stercus” in the Qenya Lexicon of the 1910s, the second gloss being Latin for “dung, manure, muck”. It was based the early root ᴱ√MUKU “cacare”, which is Latin for “defecate” (QL/63).
Neo-Quenya: I’d retain ᴺQ. múco “dung, ✱manure, muck” for purposes of Neo-Quenya based on the Neo-Root ᴺ√MUK “defecate”.
