Word History of Buckle

Noun (1)

The literal meaning of Latin word buccula was “little cheek,” but buccula was also the name for the part of a helmet that protects the cheek. Its medieval French descendant, bouclé, was the word for the boss of a shield, which looks a little like a small cheek on the face of the shield. The use of the word was later extended to belt fasteners. In this sense, the word was borrowed into English.
