The Chinese word **厄运** (èyùn, meaning "misfortune" or "bad luck") is a compound formed through the combination of two distinct morphemes: **厄** (è), which conveys the meaning of "adversity," "distress," or "hardship," and **运** (yùn), which means "fortune," "fate," or "luck." In the structural logic of Chinese word formation, this is a **modifier-head compound**, where the first character **厄** modifies and specifies the type of the second character **运**. Literally, it means "adverse fortune," where the inherent nature of the "fortune" (运) is defined as being one of hardship (厄), resulting in the unified concept of a string of bad luck or an unfortunate destiny.
