The Chinese word **发票** (fāpiào), meaning "invoice" or "receipt," is a compound noun formed by combining two meaningful characters: **发** (fā), which carries the core meaning "to issue" or "to send out," and **票** (piào), which means "ticket," "voucher," or "slip." Together, they create a logical semantic unit meaning literally an "issued ticket/voucher," perfectly describing a document that is issued by a seller to a buyer as proof of a transaction and a claim for payment. This formation follows the common Chinese morphological process of creating new words through the straightforward combination of existing, meaningful morphemes (characters).
