‘雄辩’ (xióng biàn) is an adjective describing speech that is powerfully persuasive, logically compelling, and fluently articulate. The first character 雄 (xióng) means 'masculine', 'heroic', or 'imposing'—here conveying strength, authority, and commanding presence. The second character 辩 (biàn) means 'to argue', 'to debate', or 'to reason', emphasizing logical clarity and rhetorical skill. Together, they evoke the image of a speaker who delivers arguments with both intellectual rigor and emotional impact—not merely fluent, but deeply convincing and stirring.

This word is commonly used in formal or literary contexts: political speeches, academic debates, courtroom arguments, or written essays praising someone’s rhetorical ability. It carries a positive, even admirable connotation, suggesting mastery of language and logic. While it can describe spoken or written expression, it is more often applied to spoken discourse where delivery, tone, and conviction play key roles. It is not used for casual conversation or simple politeness—it implies exceptional communicative power.
