N. Cobas loc. “Haven”
The bay north of Dol Amroth in early maps of Gondor from the 1940s (TI/312, WR/434), unnamed in the maps published in The Lord of the Rings. The name is similar to N. hobas “harbourage” and ᴱQ. kópas “harbour”. It was probably derived from the root ᴹ√KOP, a (rejected) variant of ᴹ√KHOP > hobas from The Etymologies of the 1930s (Ety/KOP, Ety/KHOP). See the entry on ᴹ√KHOP for details.
