Word Origin & History

airplane
1907, from air (1) + plane; though the original references are British, the word caught on in Amer.Eng., where it largely superseded earlier aeroplane (1873 in this sense and still common in British Eng.; q.v.). Aircraft
"airplane" also is also from 1907; airship is 1888, from Ger. Luftschiff "motor-driver dirigible."
