Origin

This character combines stone (石) on the bottom with a sound hint component (麻) on top. The stone radical makes sense for the meaning since polishing and grinding are actions performed on stone surfaces. The 麻 component serves as a pronunciation guide rather than contributing to the meaning itself. Together, the character visually suggests the action of working with stone through abrasion—something you'd do when polishing or grinding a hard material.
