The realm of Caranthir in Beleriand (S/124), a combination of dôr “land” with his name.
Conceptual Development: In Silmarillion drafts from the 1930s, this name first appeared as N. Dor Granthir (LR/265), using the earlier form of his name N. Cranthir, undergoing soft mutation according to the earlier rules of Noldorin, in which both nouns and adjectives are lenited in this position, not just adjectives as in Sindarin.
Fourth son of Fëanor, called “the Dark” (S/60). His name is a combination of caran “red” and thîr “face” (VT41/10), an adaptation of his mother name Q. Carnistir “Red-face” (PM/353).
Conceptual Development: In the earliest Lost Tales, his name was ᴱN. Cranthor (LT2/241). Tolkien change his name to Cranthir in the Lays of Beleriand from the 1920s (LB/80) and this was also his name in Silmarillion drafts from the 1930s (LR/223). N. Cranthir appeared in The Etymologies with the translation “Ruddy-face” (Ety/KARÁN, THĒ), already with essentially the same etymology as its final version.
In Silmarillion revisions from the 1950s-60s, Tolkien vacillated between Cranthir and Caranthir, ultimately settling on the latter (WJ/115).
