About
The character 脂 is a phono-semantic compound consisting of the semantic component 肉, denoting flesh or meat, and the phonetic component 旨, which suggests its pronunciation. Historically, 脂 referred specifically to animal fat, which was used in cooking, as a fuel source, and in ritual offerings. Over time, its meaning expanded to include any fatty or oily substance, leading to its application in describing plant oils, waxes, and later, biochemical lipids and cosmetic preparations like rouge and creams.
