The word 条件 is formed through the conceptual blending of two meaningful characters. 条 (tiáo) originally depicted slender, orderly items like bamboo strips, evoking the idea of listed items or clauses. 件 (jiàn) signifies a separate component or item. When combined, they create a metaphorical image of distinct, listed items or stipulations laid out in order, forming the foundational framework or set of prerequisites for something, hence the meaning "condition" or "requirement".
