The phrase "charge with" usually indicates an accusation or attribution of responsibility. Accordingly, some antonyms for this phrase include absolve, acquit, exculpate, and exonerate- all of which denote the clearing or release from responsibility for an offense. Another option could be to use a different verb altogether to describe attributing responsibility or accusations, such as "praise," "commend," or "applaud" to indicate a positive reception, or "ignore," "overlook," or "neglect" to indicate an absence of any perceived wrongdoing. Ultimately, the choice of antonym depends on the specific context and intention of the sentence.
