Etymology
The word 'collet' entered English in the 16th century from the French word of the same spelling, which itself derived from the Old French 'collet', a diminutive of 'col' (neck). The French 'col' traces back to the Latin 'collum', meaning neck. The literal sense of a "small neck" evolved metaphorically in both jewelry and mechanics to denote a small, encircling band or collar that grips another object, such as a gem or a tool shank. This evolution from a body part to a technical component illustrates a common pattern where a physical shape inspires the name for a functional object.
