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).
