Aviation is the practical aspect or art of aeronautics, being the design, development, production, operation, and use of aircraft, especially heavier-than-air aircraft. The word "aviation" was coined by French writer and former naval officer Gabriel La Landelle in 1873, from the verb "avier" (synonymous flying), itself derived from the Latin word "avis" ("bird") and the suffix "-ation".
