A noun for “horn” in The Etymologies of the 1930s derived from the root ᴹ√TARAK “horn (of animals)” (Ety/TARÁK). In The Etymologies as published in The Lost Road, Christopher Tolkien wrote that it was also used for “steep mountain pass” (LR/391), but Carl Hostetter and Patrick Wynne indicated that J.R.R. Tolkien’s actual words were “steep mountain peak” in their Addenda and Corrigenda to the Etymologies (VT46/17). This word appeared in the name N. Taragaer “Ruddyhorn”, a precursor to Caradhras in Lord of the Rings drafts of the 1940s (RS/419, 433).
Conceptual Development: A similar word G. târ “a horn” appeared in the Gnomish Lexicon of the 1910s (GL/69), equivalent to ᴱQ. taru “horn” from the contemporaneous Qenya Lexicon (QL/89).
Earlier name of Caradhras “Redhorn” in Lord of the Rings drafts from the 1940s (RS/419). It also appeared in The Etymologies from the 1930s as a combination of tarag “horn” and goer “red” (Ety/TARÁK).
