The word "玫瑰花" is a compound noun formed through morphological derivation, where the root "玫瑰" (méiguī), which itself is a disyllabic morpheme meaning "rose" (often attributed to a specific type like rugosa or a category of roses), is combined with the generic head noun "花" (huā), meaning "flower." This structure follows a common Chinese word-formation pattern of modifier-head, where "玫瑰" specifies the type, creating a more precise term that translates literally to "rose flower." It functions similarly to other floral terms like "百合花" (lily flower) and exists both to clarify the category and to fit the rhythmic and syllabic preferences of the language.
