What are the advantages of using jargon?

Answer 1

Jargon is invented as a verbal short cut so that people in a profession don't have to repeat long strings of words. It also tells other workers exactly what the person is talking about in a clear way. Jargon also helps to solidify the group as a social entity.

"Jargon" is rather a rude term for others' technical language, but I would also define it as unnecessarily pseudo-technical or pseudo-intellectual verbosity. NASA is (in)famous for this, but business managers use jargon all the time, to make the simplest concepts appear impressively complex or even opaque to their subordinates.
