The Chinese word **虚幻** (*xūhuàn*) is a compound term formed by combining two semantically related characters: **虚** (*xū*), meaning "empty," "void," or "false," and **幻** (*huàn*), meaning "illusion," "unreal," or "magical." Together, they create a **coordinated compound** where each character reinforces and nuances the other, converging on the abstract concept of "illusory," "unreal," or "fantastical." The formation follows a common pattern in Chinese where two near-synonyms are paired to express a single, often more profound or literary, idea—in this case, describing something that is not only insubstantial (**虚**) but also deceptive or dreamlike (**幻**), like a mirage or a fantasy with no basis in reality.
