How it's used
Carries a formal and authoritative tone, often appearing in written notices, official guidelines, or serious instructions. It functions as a stronger, more deliberate version of 確保. While it implies a sense of duty or necessity, it is rarely used in casual, everyday spoken conversation among friends.
Examples
Must ensure the procedure is completed smoothly.
Related words
Common mistake
Learners often mistakenly use it in casual speech where 確保 or 一定要 is much more natural. Using it in a relaxed setting can make the speaker sound overly stiff or like they are reading from a legal document.
