Semantic Clue (形旁):广 (Indicates a structure or shelter where people sit or things are based.)

坐 to sit
5. History
Liushu category: Phono-semantic (形声)
Origin: Originally formed by combining the shelter roof radical (广) with the character for sitting (坐), depicting people sitting inside a building or structure.
Semantic Evolution: Shifted from the physical act of sitting or a physical seat to serving as a counter for large, immovable structures like buildings and mountains that 'sit' firmly on the earth.
The use of 座 as a measure word evolved naturally because mountains and large edifices appear to 'sit' on the landscape just as people sit on chairs.
