wind

Wind is the moving air.

Example: The wind blows so strongly now that a person's hair goes in the person's face.

If you wind something you wrap it around and make it tight.

Example: You need to wind the string around the stick.

If you wind a clock or watch you tighten a spring inside it. This is done by turning knob. The spring powers the clock or watch as it unwinds (stops being tight).

If something winds it twists around in different directions.

Example: The road winds for miles.

If something winds down, it runs out of power and gets slower. (Like a watch that is unwinding.)
