Circumlocution literally means to talk around, and it means that a writer or speaker has used many words to talk all around a point instead of just straightforwardly stating what is meant.
Alan Greenspan (quoted in Bloomberg Businessweek, August 13-26, 2012) talks about the importance of circumlocution in his job as Chairman of the Federal Reserve:
"As Fed chairman, every time I expressed a view, I added or subtracted 10 basis points from the credit market. That was not helpful. But I nonetheless had to testify before Congress. On questions that were too market-sensitive to answer, 'no comment' was indeed an answer. And so you construct what we used to call Fed-speak. I would hypothetically think of a little plate in front of my eyes, which was the Washington Post, the following morning's headline, and I would catch myself in the middle of a sentence. Then, instead of just stopping, I would continue on resolving the sentence in some obscure way which made it incomprehensible. But nobody was quite sure I wasn't saying something profound when I wasn't. And that became the so-called Fed-speak which I became an expert on over the years. It's a self-protection mechanism... when you're in an environment where people are shooting questions at you, and you've got to be very careful about the nuances of what you're going to say and what you don't say."
Charles Dickens satirizes the typical circumlocution that occurs in politics in this excerpt from "The Circumlocution Office":
The Circumlocution Office was (as everybody knows without being told) the most important Department under Government. No public business of any kind could possibly be done at any time without the acquiescence of the Circumlocution Office. Its finger was in the largest public pie, and in the smallest public tart. It was equally impossible to do the plainest right and to undo the plainest wrong without the express authority of the Circumlocution Office. If another Gunpowder Plot had been discovered half an hour before the lighting of the match, nobody would have been justified in saving the parliament until there had been half a score of boards, half a bushel of minutes, several sacks of official memoranda, and a family-vault full of ungrammatical correspondence, on the part of the Circumlocution Office.
This glorious establishment had been early in the field, when the one sublime principle involving the difficult art of governing a country, was first distinctly revealed to statesmen. It had been foremost to study that bright revelation and to carry its shining influence through the whole of the official proceedings. Whatever was required to be done, the Circumlocution Office was beforehand with all the public departments in the art of perceiving - HOW NOT TO DO IT.
Through this delicate perception, through the tact with which it invariably seized it, and through the genius with which it always acted on it, the Circumlocution Office had risen to overtop all the public departments; and the public condition had risen to be - what it was.
