ceuran- ("k") noun "new moon" (compare Rána "moon"). The word is cited with a final hyphen, as if some final element is missing, but Rána could very well be reduced to -ran at the end of a compound. (VT48:7)

Rána
the wayward, the wanderer
Rána place-name "the Wayward, the Wanderer", a name of the moon (MR:198, MC:221, Silm); genitive Ráno in the phrase Ráno tië "the path of the Moon" (VT47:11). See also ceuran-, ránasta. According to one late source, Rána is not properly the Moon itself but is rather the "name of the spirit (Máya) that was said to abide in the Moon as its guardian" (VT42:13). The Etymologies gives Rana with a short vowel (RAN). In the pre-classical Tengwar system there presupposed, Rana was also the name of tengwa #25 (VT45:10), which letter Tolkien would later call Rómen instead.
A word appearing in notes from the late 1960s glossed “new-moon” and derived from primitive ✶keu̯rānā (VT48/7), a combination of Q. ceura “renewed” and Q. Rána “Moon”.
