noun, masculine/bʁa.saʁ/plural: brassards
armguard, brassard; armband; bracer
From bras + -ard (since at least 1549 in the spelling brassar, 1562 in the spelling brassart, and 1575 in the spelling brassard). Displaced the apparently slightly older brassal (1546), from Italian bracciale (or, less likely, Provençal brassal).
