Nuance is defined as “a subtle difference in or shade of meaning, expression, or sound”.  In terms of communication, this can be: body language, tone, double meanings, facial expressions, information deliberately excluded, eye contact (or lack thereof), or implications left to be interpreted by the receiver.

Congruency between our words and body language, tone, eye contact, and facial expressions will enforce the message.  If there is a discrepancy between our words and these non-verbal signals, the receiver of our message may miss our message and our intent.
