The word 奇异 (qíyì) is a compound adjective formed by combining two synonymous or semantically reinforcing characters: 奇 (qí), meaning "strange", "rare", or "unusual", and 异 (yì), meaning "different", "unusual", or "extraordinary". This is a classic example of a coordinating compound, where both components contribute similar meanings to create a single, more emphatic, and nuanced concept. Together, they amplify the sense of something being strikingly strange, peculiar, or remarkably extraordinary, with the whole meaning being greater than the simple sum of its parts, commonly translated as "strange", "bizarre", or "marvelous".
