Also, in Arabic countries, particularly the Mediterranean coast, a seaside esplanade. Borrowed around 1835 from French route de/en/à corniche (all three prepositions were used at the time), route on a ledge, the key word having been borrowed from Italian cornice, which we also directly borrowed for the architectural senses.
