The Chinese word 宣布 is formed by combining two characters that each contribute a layer of meaning to create a unified concept. The first character, 宣 (xuān), carries the core idea of "to declare" or "to proclaim". The second character, 布 (bù), adds the dimension of "to spread" or "to disseminate", as in laying something out publicly. When joined, the combination logically fuses these ideas: the act of declaring (宣) something in a manner that spreads it outward (布), resulting in the comprehensive meaning "to announce" or "to proclaim publicly".
