Etymology

Origin of scaffolding

First recorded in 1300–50; Middle English skaf(f)aldyng; equivalent to scaffold + -ing ¹

Explanation

The platforms and supports workers stand on while they're repairing the outside of a building is called scaffolding. Without scaffolding, it would be nearly impossible to reach the highest part of a tall structure. If you've visited a large city (or even a small one), you've definitely seen scaffolding, which sometimes surrounds an entire building. You may have even walked underneath these temporary structures, which are erected to make repairs or construct brand new buildings. Scaffolding is composed of horizontal platforms and sturdy vertical supports, and it's also used to support stagehands as they work in the theater, at outdoor concert venues, and on film sets.
