A more thorough explanation:

A gesture is a movement of the body that is used to express a thought or emphasize a point. For example, a person might wave their hand to say hello or point their finger to indicate a direction.

Another example of a gesture is when a speaker uses their hands to emphasize a point during a speech. They might make a sweeping motion with their arms to show the importance of a topic or use their hands to mimic the shape of an object they are describing.

Overall, gestures are a way to communicate nonverbally and can add emphasis and meaning to spoken words.
