莫非

莫非 is an adverb used to express a possibility or doubt, often translated as 'perhaps' or 'maybe'. It is used to question or speculate about a situation, usually with a tone of uncertainty or surprise.

The character 莫 (mò) originally meant 'not' or 'no', and 非 (fēi) means 'not' or 'non-'. Together, they form a phrase that implies a hypothetical or uncertain scenario, often used in questions or expressions of doubt.

莫非 is commonly used in daily conversations to express a guess or a possible explanation. It can also be used to soften a statement, making it less direct or more polite. For example, it's often used when someone is trying to understand why something happened or what someone might be thinking.
