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.
Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
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.
