stone
石 centers on the idea of a hard, solid mineral object: a stone. It can refer to rocks, pebbles, or stone as a material.
石 is a pictograph of a stone under a cliff or a rock. The modern form retains the angular shape suggesting a hard object.
The top stroke is like a cliff edge, and the box 口 is a stone lying beneath it. Together they form a solid stone.
For セキ, imagine a stone being used as a seat: a stone seat -> セキ. The hard stone makes a sturdy place to sit.
