The word 桥段 is formed by combining the character 桥 (qiáo), meaning "bridge", with 段 (duàn), meaning "segment" or "section". This compound directly reflects its original conceptual function in storytelling: a 桥段 is a narrative segment that acts as a bridge, transitioning between plot points or connecting story elements. The term originated as a loan translation from the English "bridge" in dramatic structure, adapted into Cantonese and later Mandarin, where the two characters together semantically encode the idea of a connecting plot device.
