Jargon in literature is usually derived from period fiction, and usually wrong. For modern writers, the problem is that writing in the jargon of previous centuries would be meaningless to modern language speakers. Educated English in the mid-late 19th century, was similar to Dickens and Jerome, but the common jargon was very different, almost archaic, and the sentence structures were quite different.In literature, however, it must be understood that jargon is necessary, to achieve authentic scenes and to deal with the storyline issues.
Examples of Jargon in Literature:
Damon Runyan- Prohibition Era jargon|
Mark Twain- American jargon
Military history- common use of contemporary military jargon (Inevitable, in context with the subject.)
