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!
Early Quenya
mul(u)-
verb.to grind
A verb appearing as ᴱQ. mul- “grind” in the Qenya Lexicon of the 1910s under the early root ᴱ√MULU “grind (fine)” (QL/63). In a nearby comparative list of roots it was given as mulu- “grind”.
Neo-Quenya: The 1968 word Q. mulë “meal” (PE17/115) indicates ✱√MUL survived in Tolkien’s later writing, so I would retain ᴺQ. mul- “to grind” for purposes of Neo-Quenya.
