The word 分辨 is formed by combining two meaningful characters: 分 (fēn), which carries the core idea of "dividing" or "separating", and 辨 (biàn), which means "to distinguish" or "differentiate". Together, they create a compound where the first character intensifies and directs the action of the second, literally picturing the mental act of "separating by distinguishing", which naturally conveys the meaning "to discriminate" or "tell apart".
