How it's used
Reserved almost exclusively for formal written contexts like police reports, news articles, or official documents. It carries a clinical and detached tone that sounds unnatural in casual conversation. Use 唔知 or 唔清楚 instead when speaking to friends or family.
Examples
The person's identity is unknown, the police are still investigating.
Why did he leave? The reason is unknown.
Related words
Common mistake
Avoid using this in spoken Cantonese as it sounds overly stiff and bureaucratic. It is not a direct substitute for 唔知 in daily life.
