The Chinese word 情绪化 (qíng xù huà), meaning "emotional" or "to behave emotionally", is a compound formed through a standard morphological process: it combines the noun 情绪 (qíng xù, "emotion" or "mood") with the suffix 化 (huà), which means "-ize", "-ify", or "to become". The suffix 化 is highly productive and functions to convert a noun or adjective into a verb or an adjective indicating a transformed state or characteristic. Thus, 情绪化 literally means "to become like emotion" or "to be characterized by emotion", describing a person or behavior that is governed by or excessively swayed by fleeting feelings rather than reason.
