MCA - ELCS - NOTES
A jargon is a language, especially the vocabulary part of a language, peculiar to particular trade, profession, or other group. As such, it’s a valuable language – in the appropriate place. Much like slang it develops as a kind of shorthand, to quickly express ideas that are frequently discussed between members of a group. In many cases a standard term may be given a more precise or unique usage among practitioners of a field. In many cases this may cause a barrier to communication as many may not understand.
Specialists need this accurate vocabulary to communicate efficiently with others in the same specialty. A specialist may unknowingly use the jargon of the trade too much, just through long familiarity with it. That would be an understandable and forgivable error, but what is unforgivable is when the writer deliberately uses heavy jargon in an attempt to impress someone.
