The word 甜美 is formed through a harmonious conceptual fusion: the first character 甜 (tián) means "sweet", primarily referring to taste, while the second character 美 (měi) means "beautiful" or "pleasing". Together, they create a compound where the literal sensation of sweetness is metaphorically extended and elevated by the notion of beauty, resulting in a meaning that conveys a delightful, heartwarming pleasantness, like a sweet flavor that is so satisfying it feels beautiful, or a pleasing experience that is as gratifying as a sweet taste.
