For students of business jargon, there was a fascinating exchange on the BBC's Today Programme earlier.
Legal & General's chief executive Nigel Wilson was being interviewed by business presenter Dominic O'Connell about the firm's half-year results, which referred to a "reduction in positive investment variance".
"What does that mean in plain English?" came the not unreasonable question.
"The returns we got from some of our investments on the stock market were less in the first half of the year than last year."
"Why don't you just say that, then?"
"I have just said it."
"But in the release, it's pretty hard to understand."
Mr Wilson apologised, saying it was "the language of our industry".
"It's the language that we've used constantly over 10 years in our releases," he added.
