Scientology terminology consists of a complex assortment of jargon used by Scientologists in conjunction with the practice of Scientology and in their everyday lives. It is difficult if not impossible to understand Scientology without understanding its terminology the way Hubbard defines it.[1][2]
L. Ron Hubbard, the founder of the Church of Scientology, created a large number of jargon terms or Scientologese to refer to various concepts in Scientology and the related practice of Dianetics. By the time he died in 1986, he had devised a thicket of language or nomenclature by means of which one and all are indoctrinated in Scientology religious lore.[3]
Hubbard's Scientology terminology consists of two types of terms:
Scientology terminology is defined in Dianetics and Scientology Technical Dictionary and Modern Management Technology Defined, colloquially known as the "tech dictionary" and the "admin dictionary". Between them, the two volumes reportedly define over 3,000 Scientology terms in over 1,100 pages of definitions.[citation needed]
The language amongst Scientologists is so thick with esoteric terms, that court cases involving Scientology sometimes need to hire expert witnesses, such as Claire Headley, to help the jury understand the evidence.[5]
Claire was able to decipher for the jury the Church's own records [...] the reports were laden with the language of Scientology that had to be decoded in such a way that anybody could understand what took place, and that was the role that [Claire] played.
