Jargon is a specialized writing style often abused by big business, certain trade industries in the legal and medical fields, federal and state governments, and institutes of education. Jargon contains "workshop words," vague figures of speech, hackneyed expressions, and pompous writing that communicators use obsessively to communicate with their peers and colleagues. Many communicators who are recipients of such jargon-wretched writing often complain about struggling to understand the written work's meaning.
Jargon creates wordiness in a document. Wordiness often creates confusion. Confusion leads to a lack of understanding. Overuse of passive voice, using bigger words instead of simpler synonyms, and lack of specifics contribute to jargon. Too much jargon in a document is said to "muddy its meaning" because readers have trouble understanding its true purpose.
