The Chinese word 开端 (kāiduān), meaning "beginning" or "outset", is a compound word formed by combining two semantically related characters: 开 (kāi), which means "to open" or "to start", and 端 (duān), which means "end", "extremity", or "point of origin". In this context, 端 is used not in the sense of a conclusion but rather as the very tip or starting point of something. Together, they create a conceptually reinforced binome where both characters contribute the idea of an initiation; 开 provides the action of commencing, while 端 specifies the precise initial point, resulting in a term that emphatically denotes the very start of an event or process.
