The word 致敬 is formed by combining two independent characters, each with its own meaning, to create a new, unified concept. The first character, 致 (zhì), carries the core idea of "to send", "to extend", or "to deliver". The second character, 敬 (jìng), means "respect", "honor", or "reverence". When joined, the formation is direct and logical: the action of "extending" (致) is directed toward the object of "respect" (敬), thus collectively meaning "to pay tribute to" or "to salute", conceptually depicting the act of sending forth one's reverence or honor toward someone or something.
