Clutter is the laborious phrase that has pushed out the short word that means the same thing. Even your dentist will ask if you are experiencing any pain. He would, in short, be himself. It's the language of the flight attendant demonstrating the oxygen mask that will drop down if the plane should run out of air. I think of Bill Mauldin's cartoon of two hoboes riding a freight car.

Verbal camouflage reached new heights during General Alexander Haig's tenure as President Reagan's secretary of state. I could go on quoting examples from various fields - every profession has its growing arsenal of jargon to throw dust in the eyes of the populace. But the list would be tedious.
