The root ᴱ√MULU “grind fine” appeared in the Qenya Lexicon of the 1910s with derivatives like ᴱQ. mulda “powdery” and ᴱQ. mulma “fine flour” (QL/63). In the contemporaneous Gnomish Lexicon, G. bloss “wheat” was derived from mol- (GL/25). This root probably as served as the basis for ᴹQ. mulo “dust” from the early 1930s (PE21/10-11). The root √MUL may have been restored later on, as evidenced by the word Q. mŭle “meal [ground grain]” from a list of words having to do with “large & small” from the late 1950s or early 1960s, replacing Q. polë of similar meaning (PE17/115).
