G'luuc'taha was a title within the Klingon civilization.
History and specifics[]
When translated, it meant "teacher of the gods". Worf once told Data that he was not a g'luuc'taha and that he was not going to tell the android about the warrior gods of the Klingon race but later relented and stated he would tell him in a private conversation. (TNG novel: Guises of the Mind)
