Did you know?

In architecture, a buttress is 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 buttress was first adopted into English as butres in the 14th century. It came to us from the Anglo-French (arche) boteraz, meaning “thrusting (arch),” and ultimately derives from the verb buter, “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.
