The word 浓度 is a modern Chinese compound term formed through morphological derivation, where the root character 浓 (nóng), meaning "thick", "dense", or "concentrated", is combined with the suffix-like character 度 (dù), which denotes a "degree", "level", or "measurement". This structure follows a common pattern in Chinese technical vocabulary, where a qualitative property (浓) is paired with 度 to create an abstract noun indicating the quantitative extent or intensity of that property, thus, 浓度 literally translates to "the degree of concentration" and is used scientifically to mean "concentration" (as in the concentration of a solution).
