💡Pro Tip

Distinguish from '违法'

'非法' emphasizes the absence of legal authorization, while '违法' (wéifǎ) implies violation of laws. '违法' can carry a moral or ethical nuance (e.g., 违法乱纪 = violating laws and discipline), whereas '非法' is strictly legal. Example: 非法入境 (illegal entry) vs. 违法犯罪 (criminal offense).

Usage with verbs

Combine '非法' with verbs like 做 (do), 进行 (carry out), or 参与 (participate in) to describe illegal actions: 非法做生意 (run illegal business), 非法进行活动 (conduct illegal activities).

📖Word Origin

Composed of '非' (not, non-) and '法' (law). '非' derives from a pictogram of a bird flying away from a nest, symbolizing negation or separation. '法' originally depicted a standard or measure, evolving to mean 'law' or 'rule'. The compound first appeared in classical Chinese texts to describe actions violating established norms.

📝Usage Notes

1. '非法' is more formal than '违法' (which can imply moral wrongdoing) and is preferred in legal documents. 2. Often used as an attributive adjective (e.g., 非法行为 = illegal act). 3. In modern Chinese, it frequently appears in news reports about crimes, regulatory violations, or social issues.
