Windy
In short
Windy describes weather conditions where air moves rapidly across the Earth's surface. It is often measured by wind speed and direction.
In plain words
Wind happens when air moves from a place of high pressure to a place of low pressure. This movement creates a breeze or a strong gale. It can be felt on your skin and can move objects.
A simple example
A light wind might gently sway the leaves on a tree. A very strong wind can blow a heavy umbrella inside out.
Why it matters
Wind affects how we dress, how ships sail, and how much energy we can make from wind turbines. It also helps spread seeds and clouds across the globe.
Easy to mix up
Do not confuse wind with weather, as wind is just one specific part of the overall weather.
