交付 (jiāo fù) is a formal verb meaning 'to hand over' or 'to deliver', especially in contexts involving responsibility, official procedures, or the transfer of objects, documents, or duties. The character 交 (jiāo) means 'to give' or 'to hand', while 付 (fù) carries the sense of 'to entrust' or 'to pay', and together they emphasize a deliberate, often official or contractual, act of transferring something from one party to another.

This word is commonly used in business, legal, logistics, and administrative settings — for example, when handing over goods to a customer, submitting documents to an authority, or assigning tasks to team members. It implies completion of a process and assumes accountability: once something is 交付, the giver is no longer responsible for it. Unlike more casual terms like 给 (gěi) or 送 (sòng), 交付 sounds professional and precise, and is rarely used in informal speech or daily household exchanges.
