The Chinese word 快餐 (kuàicān), meaning "fast food", is a compound noun formed through semantic combination: the first character 快 (kuài) means "fast" or "quick", and the second character 餐 (cān) means "meal" or "food". Together, they create a modifier-noun structure where "fast" descriptively modifies "meal", directly and logically conveying the concept of a quickly prepared and served meal, mirroring the English construction while utilizing native Chinese morphemes.
