The antonyms for the phrase "puts on trial" can be several, including "acquits," "pardons," "excuses," or "exonerates." These words are used to describe situations where someone is not held accountable for their actions, or where a specific accusation or charge is deemed unfounded. For instance, after a thorough investigation, a judge may choose to acquit a defendant due to lack of evidence, which means the defendant is not found guilty of the crime they were accused of. Similarly, a pardon is granted by an official authority to forgive a crime, meaning the person is no longer held accountable for that offense. Alternatively, the word "exonerate" means to clear someone from blame or accusation.
