The word 兑现 is formed through a conceptual blend where the first character 兑, which carries the core idea of "exchange" or "conversion" (as in converting one currency for another), is combined with the second character 现, meaning "to appear", "to manifest", or "in present form". Together, they create a metaphorical compound meaning "to make something abstract (like a promise or a ticket) visibly and tangibly appear in reality through a process of conversion", effectively picturing the act of turning a commitment into a concrete result or an instrument into cash.
