airplane (n.) Look up airplane at Dictionary.com
1907, air-plane, from air (n.1) + plane (n.1); though the earliest uses are British, the word caught on in American English, where it largely superseded earlier aeroplane (1873 in this sense and still common in British English). Aircraft as "airplane" also is from 1907. Lord Byron, speculating on future travel, used air-vessel (1822); and in 1865 aeromotive (based on locomotive) was used, also air-boat (1870).
