KK: /ˈhɛdˌwɪnd/
A type of wind that blows in the opposite direction to the movement of a vehicle, making it harder to move forward.
The pilot had to adjust the flight path because of the strong headwind.
Headwind is formed from "head" (from Old English "heafod", meaning the front or top part) and "wind" (from Old English "wind", meaning air in motion). The term describes wind that blows directly against the direction of travel, making it harder to move forward.
Think of the 'front' ('head') where the 'wind' is blowing against you, making it harder to move forward.
