IPA: //ˈkrɔːs.wɪnd//
KK: /ˈkrɔsˌwɪnd/
A type of wind that blows across the direction of travel, rather than along it.
The pilot had to adjust the flight path to account for the strong crosswind.
Crosswind is formed from "cross" (from Old English "cros", meaning to intersect or go across) and "wind" (from Old English "wind", meaning air in motion). The term describes a wind that blows across the direction of travel, intersecting it.
Imagine a wind that 'intersects' your path — that's what 'crosswind' means, a wind blowing across your direction.
