The action or process of tilting, swinging, or rocking back and forth, especially of a structure or object.
From French 'bascule' (seesaw or tilting mechanism), derived from Old French 'bas' (low) and 'cule' (implied motion). The '-ation' suffix marks this as a noun describing the process itself.
The word 'basculation' comes from the idea of a seesaw—it describes any up-and-down or tilting motion, and it's especially used in architecture and engineering for structures designed to move.
