An indexing radical for the nose and the sense of smell. Built from 自 (originally 'nose', a pictograph of the organ) plus 畀 as phonetic. Productivity is small — 鼾 (snore), 鼽 (stuffy nose), 齆 (nasal voice) — and modern compounds typically use 鼻 itself in front of another character (鼻孔 nostril, 鼻涕 mucus, 鼻塞 stuffy nose).
