What is the definition of unwritten communication?

The term "unwritten communication" isn't a standard term in communication studies. It's more likely that you are referring to nonverbal communication, which is the transfer of information through means other than written or spoken words.

Here are some examples of nonverbal communication:

* Body language: Facial expressions, posture, gestures, eye contact.

* Paralanguage: Tone of voice, pitch, volume, speed, rhythm.

* Proxemics: Personal space and distance.

* Haptics: Touch.

* Appearance: Clothing, hairstyle, accessories.

* Environment: Physical surroundings and atmosphere.

Nonverbal communication can be just as powerful as verbal communication, and it often plays a crucial role in conveying emotions, attitudes, and intentions. It's important to be aware of both verbal and nonverbal cues when communicating effectively.

If you can provide more context or examples of what you mean by "unwritten communication," I can give you a more precise answer.
