verb / noun

collapse

kuh-LAPS/kəˈlæps/

To fall down suddenly through loss of support or strength.

The wooden shed collapses as its broken supports buckle beneath the roof.

A small wooden shed caught mid-collapse: its broken supports buckle outward while the roof drops into the folding walls, with falling boards and a small puff of dust making the sudden downward movement visible.
Etymology

The pieces evoke “falling together,” as a structure loses support and falls into a mass. That physical image extended to plans or institutions failing completely.
