The word 奶酪 is formed by combining two characters: 奶, which means "milk", and 酪, which refers to a "fermented or curdled dairy product". Together, they create a compound word where 奶 establishes the foundational substance (milk), and 酪 specifies the particular processed form derived from it, resulting in the meaning "cheese". This formation visually and conceptually links the source material with the end product, encapsulating the idea of cheese as a solidified dairy item without needing to elaborate on linguistic rules.
