About
The character 脂 is structurally a phono-semantic compound, integrating the meat radical 月 to signify its relation to flesh or bodily substances with the component 旨 primarily serving as a phonetic indicator. Etymologically, its earliest meanings were centered on animal-derived fats and greases, which were essential materials for lighting, lubrication, and food preparation in ancient societies. Over time, the term's application extended beyond animal products to include plant-based oils and a wider array of fatty or creamy substances, thereby encompassing biological lipids and refined products like ointments and cosmetics. This semantic broadening, while maintaining the core association with greasy consistency, is evident in modern compounds such as 脂肪 for bodily fat and 脂粉 for face powder, illustrating a gradual conceptual shift from specific material origins to a more generalized category in scientific and everyday language.
