‘补发’ (bǔ fā) is a compound verb meaning 'to resend' or 'to issue belatedly.' It combines 补 (bǔ), meaning 'to make up for,' 'to supplement,' or 'to compensate,' and 发 (fā), meaning 'to send out,' 'to issue,' or 'to distribute.' Together, they describe the action of delivering something—such as documents, payments, goods, or notifications—that was missed, delayed, or omitted in its original scheduled time.

This term is commonly used in administrative, workplace, and customer-service contexts—for example, when a company resends an expired invoice, a school issues a replacement student ID, or HR reissues a forgotten salary slip. It implies intentionality and corrective action rather than accidental repetition. While often used formally, it can appear in everyday speech when discussing delayed deliveries or official paperwork. Note that ‘补发’ always refers to a second or corrective issuance—not the first—and carries no implication of apology, only functional resolution.
