Inherited from Old Galician-Portuguese brasa, from Vulgar Latin *brasa, of uncertain origin, perhaps Germanic, from Gothic *𐌱𐍂𐌰𐍃𐌰 (*brasa, “glowing coal”), from Proto-Germanic *brasō (“gleed, crackling coal”), from Proto-Indo-European *bʰrewh₁- (“to seethe, boil, brew”), or from *bʰres- (“to crack, break, burst”). Cognate with Fala and Portuguese brasa.
