Depurgate means to purify or cleanse something, but its antonyms indicate its opposite meaning. To dirty, contaminate, corrupt, taint, or pollute are the antonyms of depurgate. When something is depurated, it is free from impurities, but its antonyms indicate that it is full of impurities, pollutants, or harmful substances. For example, when pollutants are added to clean water, it loses its depurated state and becomes contaminated. Similarly, when ideas or thoughts are contaminated with prejudices or biases, they lose their depurated state and become corrupted. Therefore, it is essential to depurgate our thoughts, actions, and surroundings to maintain a clean and healthy environment.
