How it's used
務須 carries a formal, authoritative tone that is rarely used in casual daily speech. It is most commonly encountered in written notices, official documents, or when someone is giving a very serious, stern instruction. In everyday conversation, people prefer using 一定要 or 必須.
Examples
This matter must be handled as soon as possible.
You must go and ask clearly in person.
Related words
Common mistake
Learners often use this in casual settings where it sounds overly dramatic or stiff. It is not a direct substitute for the common 一定要 in friendly advice or casual requests.
