The jargon I really loathe is the generalised management speak which is so prevalent. Management speak is truly awful and only complicates our world, while bringing no real benefits.

I think some dedicated fans of jargon use it with the best of intentions. It demonstrates knowledge of their specialist subject and, as you say, gives people a shared vocabulary within their professional group.

This is fine when they’re communicating between themselves, but if the outside world needs to understand, there can be issues.

I like your point about working with people to find the best way to explain ideas, rather then fighting a lone battle against jargon.

Thanks again for your ideas.
