Most animals communicate with each other in some way. Dogs bark at those they perceive as a threat in order to communicate their hostility and in some cases the threat that they will attack if provoked; bees have a pouch in which they carry the scent of their hive so as to identify themselves as members of the community.

From here, the intention of the person speaking breaks it down into still further categories depending on whether they are trying to persuade the listener or listeners to think or act in a certain way, to convey information in the clearest manner possible, or even to entertain. However, in many cases, the intentions of the speaker will overlap: speakers may want to persuade, inform, and entertain their audiences all at the same time. Sometimes, they may even be unaware of what their true intentions are themselves.
Non-verbal communication is the type that is more similar to what the dogs and bees mentioned above do.

Probably the most ubiquitous example of non verbal communication is that of facial expressions. For example, when a person rolls their eyes at someone, they are expressing skepticism about what the speaker said. They are not using any words to convey this message, but using their
