The Chinese word **叛乱 (pànluàn)**, meaning "rebellion" or "revolt," is a coordinative compound formed by combining two characters with closely related meanings. The first character, **叛 (pàn)**, inherently means "to betray" or "to rebel," focusing on the act of defiance against authority. The second character, **乱 (luàn)**, means "chaos," "disorder," or "turmoil," describing the resulting state. When combined, they create a single noun that encapsulates the entire concept of a **betrayal that leads to chaos**, effectively meaning an organized, violent uprising against a ruling power. This structure, where two synonyms or complementary morphemes reinforce each other, is common in Chinese for forming abstract or complex nouns.
