The Chinese word 药丸 (yàowán), meaning "pill" or "tablet", is a straightforward compound noun formed by combining two meaningful characters: 药 (yào), which means "medicine" or "drug", and 丸 (wán), which means "pill", "ball", or "small round object". In this modifier-head structure, the first character 药 specifies the category or purpose (medicine), while the second character 丸 denotes the physical form (a small, round pill). Together, they create a precise and logical term where the whole meaning is directly derived from the sum of its parts, essentially, a "medicine pill".
