Apparently another name for Andrast (UT/175, 214 note #6). This name seems to be a combination of ras(t) “cape”, morn “black” and the nasal mutation of till “point” (as suggested by David Salo, GS/389).

Conceptual Development: This name appeared on Tolkien’s private map of Beleriand (WJ/184) but not in the maps published in The Silmarillion. It is also mentioned in Tolkien’s Quendi and Eldar essay from 1959-60 (WJ/379).

angast
place name. Long Cape
An earlier form of Andrast appearing in Tolkien’s essay on the “Rivers and Beacon-hills of Gondor” (VT42/8, 15), composed between 1967-9 (VT42/5). The second element of this name appears to be the lenited form gast of an otherwise unattested word cast “cape”, perhaps related to the root √KAS “head”, as suggested by Carl Hostetter (VT42/28, note #16).
Andrast
Andrast
Andrast (earlier form Angast) is a Sindarin name meaning "Long Cape".
A cape in southwest Gondor translated “Long Cape” (UT/214, note #6). This name is a combination of and “long” and ras(t) “cape”.
Conceptual Development: An earlier form of this name Angast appeared in Tolkien’s essay on the “Rivers and Beacon-hills of Gondor” (VT42/8, 15), composed between 1967-9 (VT42/5). The revised name Andrast is mentioned in notes for the posthumously published story “Aldarion and Erendis” (UT/214, note #6). The name was first published in the Pauline Baynes poster map of Middle-earth, made in consulation with Tolkien in 1969 (RC/lxiv).
