About

The character (biǎn) is a phono-semantic compound: the stone radical (shí) on the left indicates it is made of stone, while the right component (biǎn, 'flat') suggests both the pronunciation and the object's flat shape. Historically, it referred to a stone mounting block set near doorways or in courtyards, used as a step to help people mount horses or get into carriages. As horse-drawn transport declined, these blocks disappeared, and the character fell out of use; today it appears only in classical literature and historical records.
