bracketing

The word 'bracketing' originates from the architectural term 'bracket', a supportive projection from a wall. This term entered English in the late 16th century from the French braguette, which initially meant 'codpiece'—a garment support—and later came to denote a type of architectural support. The semantic connection lies in the concept of a structure that holds, supports, or encloses something. The addition of the Old English agentive suffix '-ing' transforms the verb 'to bracket'—meaning to enclose within brackets or to group together—into a noun describing the process or result of that action. Thus, the modern abstract meaning of 'grouping or classifying items together' logically extends from the physical idea of placing them within supportive, enclosing marks or categories.
