What does calumnious mean?
Calumnious describes language that is not merely inaccurate but deliberately and maliciously false, spoken or written with the intent to destroy someone's good name. A calumnious accusation, rumour, or article asserts things its author knows to be untrue, making the word stronger than terms like "misleading" or "exaggerated" and placing it alongside "slanderous" and "defamatory." It functions almost exclusively as an adjective applied to statements, charges, pamphlets, gossip, or campaigns of abuse — for example, "the calumnious rumours spread by his enemies." The word is formal and somewhat literary, appearing more often in legal contexts, serious journalism, and historical prose than in casual conversation, where simpler synonyms usually take its place. Its Latin ancestry, tracing back through calumnia (a term for false accusation and trickery), gives it an air of classical authority, which is precisely why writers reach for it: it condemns falsehood while signalling that the speaker recognises defamation for what it truly is.

Calumnious comes from a Latin word for trickery and deception — so when you call a rumour calumnious, you're literally calling it a con job.
