Middle Primitive Elvish

doʒ

root. night

A root in The Etymologies of the 1930s glossed “night” that (along with ᴹ√DOM) was the basis for the ᴹQ. lóme/N. “night” (Ety/DOƷ). It replaced some rejected variants ᴹ√LOƷ and ᴹ√DAW (EtyAC/LOƷ). Many of the derivatives of ᴹ√DOƷ were later assigned to other roots: N. dûr “dark” became S. dûr “dark” < √NDU “under, down” in notes from the late 1950s or early 1960s (PE17/152) and ᴹQ. lóna “dark” became Q. lúna (PE17/22). There are no signs of ᴹQ. “night” and N. daw “night-time, gloom” in Tolkien’s later writing. Future derivations of Q. lómë/S. only mention the root √DOM (PE17/152; PE22/153) and thus ᴹ√DOƷ may have been abandoned.

In a message to the Elfling mailing list from July 2012, the user Iipitaka suggested there might be a later root DU serving as the basis for Q. lúna “dark” and Q. lúmë “darkness”, though the latter might instead be from √LUM. Such a root DU is not attested in Tolkien writings, but if it existed, it could be a later iteration of ᴹ√DOƷ.
