Hubbard's terminology is used so thoroughly in Scientology as to render many church materials incomprehensible under a standard English reading using only an English dictionary as reference. Scientologists will study hard to learn all this terminology, since one of Hubbard's teachings is that "...the only reason a person gives up a study or becomes confused or unable to learn is because he or she has gone past a word that was not understood." It is also used extensively in offshoots of Scientology, such as the Narconon drug rehabilitation program or the Applied Scholastics education program. Scientologists often use Scientology terminology in non-Scientology contexts as well, such as in social or office situations. This can actually wreak havoc when a member of the public hears the word "communication" coming from a Scientologist and he thinks he understands what "communication" means, but the word "communication" in Scientology is a highly "technical" term which has very little to do with what is generally considered communication. "Communication" is not the only word that has a special meaning in Scientology but it is the most important one. There are other words such as "technology", "administration", "logic", "ethics", "control", etc. that have a specially unique meaning in Scientology.
