‘交代’ is a verb meaning to explain something clearly, especially instructions, responsibilities, or background information, or to entrust someone with a task or duty. The character 交 (jiāo) means 'to hand over' or 'to interact', and 代 (dài) means 'to represent' or 'to substitute'; together, they convey the idea of transferring responsibility or information from one person to another. It’s commonly used in work settings, family conversations, or formal contexts where clarity and accountability matter.

This word often implies seriousness or importance — for example, a manager might 交代 tasks before leaving the office, or a parent may 交代 safety rules before a child walks home alone. While it can sound neutral, tone and context determine whether it feels supportive or stern. Unlike casual verbs like ‘say’ or ‘tell’, 交代 suggests intentionality and expectation of follow-through.
