A movement of the body or a part of the body that emphasizes or conveys a particular emotion or idea.
Emphatic gestures can be used to emphasize a point in speech or to convey emotions such as joy, anger, or frustration. They can also be used to communicate intentions, such as a desire to leave or get someone's attention.
Some examples of emphatic gestures include:
* _A waving motion of the hand_ to indicate goodbye or to get someone's attention.
* _A clenched fist_ to indicate anger or frustration.
* _A shrug of the shoulders_ to indicate indifference or uncertainty.
* _A thumbs up_ to indicate approval or agreement.
* _A thumbs down_ to indicate disapproval or disagreement.
Emphatic gestures are often used in conjunction with other forms of communication, such as speech, to convey a more complete message.
