The term "un-candidness" refers to the state of being dishonest or insincere. Its antonyms, however, denote characteristics such as frankness, candor, openness, and transparency. Someone who is candid displays honesty and forthrightness in their words and actions, while someone who lacks candor is more likely to be evasive, deceptive or disingenuous. Other antonyms for un-candidness include sincerity, genuineness, and authenticity. These traits are highly valued both personally and professionally, as they promote trust and credibility. Thus, it is important to recognize and foster candidness in oneself and others to achieve more positive and authentic interpersonal relationships.
