The word 美貌 is formed by directly combining two meaningful characters: 美 (měi), which means "beautiful" or "beauty", and 貌 (mào), which means "appearance" or "looks". Together, they create a compound where the first character describes the quality of the second, resulting in the intuitive and immediate concept of "beautiful appearance" or "physical beauty". This formation is a natural fusion of an attribute with its subject, making the meaning of the whole word clear from the sum of its visible parts.
