Did you know?
The word buttress first budded in the world of architecture during the 14th century, when it was used to describe an exterior support that projects from a wall to resist the sideways force, called thrust, created by the load on an arch or roof. The word ultimately comes from the Anglo-French verb buter, meaning "to thrust." Buter is also the source of our verb butt, meaning "to thrust, push, or strike with the head or horns." Buttress developed figurative use relatively soon after its adoption, being applied to anything that supports or strengthens something else. No buts about it: the world would not be the same without buttresses.
