The word 诱饵 is formed by combining two characters, each contributing a core idea that merges into a single, more specific concept. The first character, 诱 (yòu), carries the meaning of "to lure" or "to entice". The second character, 饵 (ěr), means "bait" or "food used as bait". Their combination is not merely a sum of parts, but a conceptual fusion where the first element describes the purpose or action, and the second provides the physical object used for that action. Thus, together they create the complete idea of a "lure", an object (bait) whose essential and defining function is to entice.
