The Chinese word **发怒 (fānù)**, meaning "to become angry" or "to fly into a rage," is a compound verb formed through a standard grammatical construction. It combines the verb **发 (fā)**, which in this context functions as a causative prefix meaning "to issue," "to send out," or "to enter a state of," with the core character **怒 (nù)**, which means "anger" or "wrath." Therefore, the term literally and conceptually depicts the act of "issuing forth anger" or "entering into a state of wrath," where 发 initiates and 怒 names the resulting emotional state. This **verb + object/result** structure (发 + 怒) is a common pattern in Chinese for forming dynamic verbs that describe the onset of a specific condition.
