The words are articulated sounds with which you send concepts. If we talk about being one in front of others, along with the words verbal, we provide many other communication messages is “non-verbal” and “paraverbal”.
The non-verbal messages are given by gestures, by the physical environment and distance.
The paraverbal messages are related to the quality of the voice tone, rhythm, volume.
