Credit is defined as the trust or belief that people have in someone's ability, honesty, or truthfulness. Dis credit, on the other hand, is the opposite of that belief, questioning someone's ability, honesty, or truthfulness. Antonyms of discredit therefore include words such as credibility, integrity, respectability, and reliability. These are all qualities that denote trust, belief, and confidence in a person or an entity. When someone is discredited, their reputation and standing may suffer, which can lead to a loss of credibility and trust. On the other hand, building one's credibility and integrity can lead to greater trust, respect, and opportunities to succeed.
