Both men and women can be witches, brujos and brujas respectively. Brujos is the plural term that can mean either a group of male witches or both male and female witches. The female witch is considered the most powerful, and traditional brujos believe that the female passes down the sacred bloodline or spiritual bloodline (matriarchal lineage). This means that the line is inherited from a female but ends with a male.
The word bruja is believed to derive from bruxa, which is from the Celto-Iberian dialect in Spain evolving to what is known today as Gallego. It shares its roots with Portuguese. The present day Portuguese use the term bruxa. The original meaning is roughly, evil or unwholesome night-bird, but has evolved both in Portuguese and in Spanish to mean simply 'witch'. _Wikipedia
