A tower raised by Finrod on the cape of Eglarest, translated “White Horn Tower” (S/120, SI/Barad Nimras). It is a combination of barad “tower”, nim “white”, and rass “horn” (SA/barad, nim, ras).
Conceptual Development: In Silmarillion drafts from the 1930s, this tower was first named N. Tindobel (LR/129, 265). In Silmarillion revisions from the 1950s-60s, Tolkien changed the name to the Tower of Ingildon (WJ/118, notes §90) and later to its final form Barad Nimras (WJ/197-8, notes §120).
white-horn tower; barad (“tower”), nimp (“white”) + ras (“horn”) The original form of ras would probably be rass in TA S with the final s dropped at the end of a polysyllable [HKF].
