Etymology

The word "brace" traces back to Old French brace (meaning "arm"), derived from Latin bracchium (also "arm"). The original sense of "clasping with arms" evolved metaphorically into "support" (like arms holding something up) and later "a pair" (from the idea of two arms). The silent "-e" is a common Middle English suffix.
