‘Tián wèi’ literally combines 甜 (tián), meaning ‘sweet’, and 味 (wèi), meaning ‘taste’ or ‘flavor’. Together, they form a noun referring specifically to the sensory experience of sweetness — one of the five basic tastes recognized in Chinese culinary and physiological contexts. It describes the taste quality itself, not the food or substance causing it; for example, you might say a fruit has strong 甜味, or that medicine is masked with sugar to reduce its bitterness and add 甜味.

This term appears frequently in discussions about food, nutrition, health, and cooking. It’s neutral in register and commonly used in both everyday speech and formal contexts like dietary advice or food labeling. Unlike the verb 甜 (to be sweet), 甜味 focuses on the perceptual property — it’s what you detect on your tongue, not an inherent trait of the object. It often appears in compound terms like 甜味剂 (sweetener) or 甜味感受器 (sweet taste receptor).
