控诉 (kòng sù) is a formal, often emotionally charged verb meaning 'to accuse publicly' or 'to denounce forcefully,' typically in contexts involving injustice, abuse, or serious wrongdoing. The first character 控 (kòng) means 'to control' or 'to charge (legally),' while 诉 (sù) means 'to state,' 'to tell,' or 'to appeal.' Together, they convey the sense of formally and passionately laying out grievances—often before an authority, audience, or tribunal—not just privately complaining but making a public, moral, or legal claim.

This word appears frequently in news reports, historical accounts, courtroom narratives, and human rights discourse. It implies gravity, legitimacy, and moral urgency; it’s rarely used for minor disputes or casual criticism. Speakers often pair it with objects like 'crimes,' 'abuses,' or 'injustices,' and it commonly appears in passive constructions (e.g., 被控诉) or as part of official statements (e.g., 向法院控诉). Its tone is solemn and weighty—never colloquial or lighthearted.
