可不

可不 is an adverb that means 'certainly' or 'of course,' often used to emphasize agreement or confirmation. It conveys a sense of strong affirmation, similar to 'indeed' or 'surely' in English.

The character 可 (kě) originally meant 'can' or 'possible,' and it later developed the meaning of 'should' or 'ought to.' 不 (bù) means 'not.' Together, 可不 forms a phrase that expresses certainty, often in response to a question or statement.

Used in daily conversation, 可不 adds emphasis and conviction. It is commonly used in informal settings to show agreement, approval, or to reinforce a point. The phrase is often used with a rising tone to indicate surprise or emphasis.
