Sindarin name for the “Bay of Belfalas”, appearing in a rejected section of Tolkien’s essay on The Rivers and Beacon-hills of Gondor (VT42/15). It is a combination of côf “bay” and Belfalas. The section was rejected because Tolkien revised the history of the name Bel (UT/247), so it is possible that the name of the bay remained valid.

Conceptual Development: In draft maps for The Lord of the Rings from the 1940s, this bay was labeled N. Cobas “Haven” (TI/312, WR/434). The bay was unlabeled in the maps for the published version of The Lord of the Rings.

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.
