The word 发布 is formed by combining two characters, each contributing a key action to create a unified concept. The first character, 发 (fā), carries the core meaning of "to send out" or "to issue". The second character, 布 (bù), means "to spread" or "to announce", often with a sense of making something widely known. When joined, the sequence 发 then 布 logically depicts the process of first issuing something (like information, an order, or a product) and then causing it to be disseminated or proclaimed to the public, thus forming the complete idea of "to release" or "to publish".
