How it's used

This structure emphasizes a strong sense of necessity or an unavoidable outcome. It carries a more dramatic or determined tone than simply using 要 or 必須. It is often used when expressing a personal resolve or a situation where no other alternative is acceptable.

Common mistake

Learners often try to insert extra words between the non-negated verb and the final 不可, but the structure is fixed. Ensure the verb or action immediately follows the first part of the pattern.
