A word appearing as ᴱQ. mulma “fine flour” in the Qenya Lexicon of the 1910s under the early root ᴱ√MULU “grind (fine)” (QL/63).

Neo-Quenya: The 1968 word Q. mulë “meal” (PE17/115) indicates *√MUL survived in Tolkien’s later writing, so I would retain ᴺQ. mulma for “fine flour”. But I would use it only for very powdery flour, and would use [ᴹQ.] pore (Ety/POR) for ordinary “flour”.
