Emblems in speech
Emblems are certain gestures which have a specific meaning attached to them. These meanings are usually associated with the culture they are established in. Using emblems creates a way for humans to communicate with one another in a non-verbal way. An individual waving their hand at a friend, for example, would communicate "hello" without having to verbally say anything.
