IPA: /ˈɛəpleɪn/
KK: /ˈɛrˌpleɪn/
A type of vehicle that can fly through the air, usually with wings and powered by engines or propellers.
The airplane took off smoothly from the runway.
Airplane is formed from "air" (from Old English "aer", meaning the atmosphere or sky) and "plane" (from Latin "planus", meaning flat or level). The word "airplane" refers to a flat or level vehicle that travels through the air.
Think of 'air' as the atmosphere and 'plane' as something flat — an airplane is a flat vehicle that travels through the air.
