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.
