cûl bîn

place name. Little Load

A mountain near Tarlang’s Neck, mentioned only in Tolkien’s Nomenclature of the Lord of the Rings, where he translated the name as “Little Load” (RC/536). It appears to be a combination of cûl “load” and the lenited form bîn of the (otherwise unattested) adjective pîn “little” (RC/536).
