N. Cobas loc. “Haven”
The bay north of Dol Amroth in early maps of Gondor (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 before it was changed to ᴹ√KHOP > hobas (Ety/KOP, Ety/KHOP).
