Being indignant refers to being angry or offended due to an unfair treatment, an insult, or injustice. Antonyms of being indignant include being calm, composed, patient, peaceful, content, and satisfied. When you encounter a situation that might normally make you feel indignant, try adopting a calmer attitude and approach the problem logically. Maintain your composure and choose a peaceful solution rather than an angry one. This will lead to better outcomes and a more positive experience. It's important to remember that working towards a solution calmly is much more effective than being indignant and angry.
