The Chinese word **背弃 (bèiqì)**, meaning "to abandon" or "to betray," is a compound formed through **semantic coordination**. It combines two characters with related meanings: **背 (bèi)**, which literally means "the back" but here carries the figurative sense of "to turn one's back on" or "to violate," and **弃 (qì)**, which means "to discard" or "to forsake." Together, they create a single, more nuanced verb where the two meanings reinforce each other; the act of turning away is intrinsically linked with the act of throwing away or deserting, often in the context of principles, promises, or people. This method of word formation, where two synonymous or complementary morphemes are paired, is very common in Chinese to express abstract or complex actions with clarity and emphasis.
