Inherited from Old Spanish sufre, from Latin sulfur, sulphur, sulphure, from Proto-Indo-European *swelplos, from the root *swel- (“to burn, smoulder”). Compare modern French soufre. The initial a- could have appeared due to a misinterpretation of the expression piedra sufre (literally “sulfur stone”).^[1]
