常見錯誤

❌I have many duties to do my boss.

用法筆記

Most common in formal and legal contexts with phrases like 'duty of care,' 'duty of loyalty,' or 'fiduciary duty.' This sense differs from sense 2 (MORAL OBLIGATION) because it is grounded in a specific relationship or legal framework rather than general conscience.
