| | Old Chinese |
| 鞭 | *pen |
| 鯾 | *pen |
| 箯 | *pen, *ben |
| 便 | *ben, *bens |
| 緶 | *ben, *peːnʔ |
| 楩 | *ben, *benʔ |
According to Shuowen, an ideogrammic compound (會意 / 会意): 亻 (“person”) + 更 (“to change”) – to change one's posture to make oneself comfortable.
Alternatively, this may be the original character for 鞭 (OC *pen, “to whip”), from 人 (“person”) + 𠓥 (“whip”), as seen in the bronze script.
