What term describes the ability to communicate effectively and avoid offense in interpersonal relations?

The term that best describes the ability to communicate effectively and avoid offense in interpersonal relations is "tact." Tact involves an understanding of how to convey messages sensitively and appropriately, taking into account the feelings and perspectives of others. It allows individuals to navigate conversations in a way that is considerate and diplomatic, particularly in delicate or potentially contentious situations.

Having tact often means being aware of social cues and the emotional context of discussions, which helps in maintaining cordial relationships and fostering a positive atmosphere. While empathy, respect, and confidence are important qualities in interpersonal interactions, they do not specifically encapsulate the idea of communicating in a manner that is both effective and non-offensive. Tact is focused on the finesse of communication, ensuring that messages are delivered in a way that is mindful of how they may be received by others.
