What does it mean to “cast aspersions”?

To cast aspersions is to make damaging or disparaging remarks about someone or something. It is a way of expressing disapproval or doubt without directly accusing someone of something. It is often used to imply that someone is guilty of some kind of wrongdoing or is otherwise unworthy of respect. It can be used to undermine someone's reputation or credibility without actually providing any evidence of wrongdoing. Aspersions can be cast in a variety of ways, including through gossip, innuendos, and other forms of verbal or nonverbal communication. Aspersions can be cast in a subtle or overt manner, and they can have a lasting negative impact on someone’s reputation.
