The correct answer to this open question is the following.
Communication is social in that it involves people and interactions, whether face-to-face or mediated. Can you think of a few more categories for the social patterns of human communication?
Yes, for instance, nonverbal communication also is a form of human communication. Here we are talking about gestures or the posture people have while communicating with others. There are also other elements such as the tone of the voice, the volume of the voice, or the rhythm. Experts call this paralanguage.
Another important element could be the way we dress. Our clothing can also communicate part of our personality, and it could be a regional dress from our community, an executive suit and tie in the corporate world, a street fashion apparel that transmits rebellion, or any other forms in which our clothing transmits who we are.
