doublespeak

Intentionally deceiving language. Not an outright lie or a tactful euphemism, but systematic use of ambiguous, evasive words and sentence structures to say one thing but mean something else. Commonly associated with bureaucracy, military, and politics, it is often practiced in commerce also as a calculated attempt to (1) avoid or shift responsibility, (2) distort reality by making the bad, negative, or unpleasant look good, positive, or pleasant, and vice versa, and (3) confuse by using unfamiliar or concocted jargon. See collateral damage as an example. Also called doubletalk or doublethink.
