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 noun appearing as G. mail “flour” in the Gnomish Lexicon of the 1910s, derived from the early root ᴱ√MILI which had to do with “seed” words (GL/56; QL/61). This word seems to be the result of a-fortification: the insertion of an a in ancient word forms. Tolkien marked the word with a “?” indicating he was uncertain of it.
Neo-Sindarin: I would adapt this word as ᴺS. maul “flour” using a-fortification of the (hypothetical) root √MUL that seems to be the basis for Q. mulë “meal” from the 1960s.
