Feeling sick or nauseous due to the movement of an airplane while flying.
She felt airsick during the flight to Paris.
Airsick → The word is formed from "air" (from Old English *aer*, meaning the atmosphere or sky) and "sick" (from Old English *sēoc*, meaning ill or unwell). The term "airsick" describes the feeling of being unwell due to the motion or conditions in the air, typically while traveling by airplane.
Imagine feeling 'ill' ('sick') because of the 'atmosphere' ('air') around you — that's what airsick means.
