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.
