Impeach is a powerful word with serious implications, usually associated with politicians or public officials being accused of wrongdoing in their official capacity. But there are other verbs that can be used as substitutes, each with its own connotations and shades of meaning. "Accuse" generally implies a less formal and more general accusation, while "indict" and "charge" are legal terms that suggest a more specific and formal accusation. "Censure" and "rebuke" are words that suggest a mild disapproval or reprimand. "Denounce" has a more forceful connotation and implies an open condemnation or criticism. Ultimately, the choice of word will depend on the context and the speaker's intention.
