Edward Purkis Frost's 1902 ornithopter

An ornithopter is an aircraft that flies by flapping its wings like a bird.

The term orthopter is sometimes used synonymously but can be distinguished (as in Ventou-Duclaux and Robert, 1911, Bases et méthodes d'études aéronautiques, pp. 375–381) by distinguishing between flat flapping surfaces and flexible birdlike "wings". While both terms share the root "-pter" meaning wing, "orni-" means bird, whereas "ortho" means straight, and connotes the order of insects called Orthoptera (crickets, grasshoppers).
