Brindled \BRIN-did\ , adjective;
1. Gray or tawny with darker streaks or spots
This word dates to the 1670's from Middle English brended from the noun bren ("brown color"), which was a back-formation of the past participle brennen. Brennen meant "burn," but it could have also meant "marked as though by branding or burning."
