A root mentioned in Primitive Quendian Structure: Final Consonants from 1936 as the basis for the 1930s genitive suffix ᴹQ. -n. In later writings, the Quenya genitive suffix became Q. -o, and the dative suffix -n was given a new etymology from √NA/ANA, so likely ᴹ√ENE fell out of Tolkien’s favor for this particular use.
