A word appearing in The Etymologies of the 1930s as N. cûran “crescent moon”, a combination of N. cû “crescent” and N. Rhân “moon” < ᴹ✶Ranā (Ety/KUƷ, RAN). In The Etymologies as published in The Lost Road, Christopher Tolkien gave the form as cúran, but according to Carl Hostetter and Patrick Wynne the actual form was cûran (EtyAC/KUƷ).

Neo-Sindarin: If adapted to Neo-Sindarin, this word would probably become ᴺS. cúron, analogous to S. cýron “new-moon” (VT48/7), with S. Raun < *rānā reduced to -ron as usual in polysyllables.
