A firth (inlet, estuary) from Belegaer into Dor-lómin (S/89). The meaning of the name is unclear.

Conceptual Development: The name N. Drengist appears in Silmarillion drafts from the 1930s (SM/268), but the closest Tolkien ever came to translating it was in a name list with Elvish-Old English correspondences, where it was glossed O.E. “Nearufléot”, in Modern English “Narrow Firth/Estuary” (SM/210). This “translation” may simply be descriptive, however.
