What is a “Warlock?”
 
It’s been mistakenly used to define a male witch. Although it’s been used to define a male magician or witch by the inquisition, (From this perspective it can be said that as the word “witch”, the word “warlock” has also undergone a negative meaning shift)  in modern Wicca, it means “Oath breaker”, covering both male and female sexes.

There are two opinions about the origin of the word. One claims that the word is Anglo-Saxon based, and comes from the Old English word “waerloga” (betrayer: waer, loga: liar).
The second one claims that the word is Scandinavia based and comes from “var’lokkur” (var: spirit, lokkur: song or the one who communicates with spirits). It has been described in this way in the “Saga of Eric the Red” which has been dated to the 14th century.
 
Although it’s a controversial word, because of the negative meaning it evokes, usually the first point of view is accepted.
