A building with sails or vanes that turn in the wind and generate power to grind grain into flour.
or

Move (one's arms) around in a circle in a manner suggestive of the rotating sails or vanes of a windmill.

i think it's the second one, am i correct?

but this is relating to farms or a country

so is it the second one???

No, it's the first one. Windmills used to be used by all farmers. They are still used by Amish farmers because they do not use electricity.

They are both right.

Yes, you are correct! The second definition of "windmill" refers to the action of moving one's arms around in a circle, imitating the motion of the rotating sails or vanes of a windmill. This motion is often associated with certain acrobatic or gymnastic movements, like in martial arts or dance. It is commonly used to describe a specific technique called a "windmill" or "windmill kick," where a person swings their legs in a circular motion while maintaining a handstand or other balancing position.
