Word History

River comes via Old French rivere from Latin riparius, from ripa 'bank of a river'. It is related to arrive, which originally meant 'bring a ship to shore'. It is also connected to the word rival, which derives from Latin rivalis, originally meaning 'person using the same stream as another', from rivus 'stream'. Riviera, an Italian word ultimately derived from Latin ripa, preserves the original meaning of 'land next to water'.
