New word of the day (and other delightful linguistic discoveries)

[Morrigoon]

I was reading an article a little bit ago and came across this gem of a word, which I intend to sock away for future use: sangfroid

In context:

Cool, calm, and collected, Federal Reserve Chairman Ben S. Bernanke is driving Wall Street batty. When traders scream about a recessionary "credit crunch," the former professor acknowledges their concerns but predicts continued economic growth. When they plead for easier money, Bernanke and his fellow rate-setters firmly hold the line. "Scandalous," sputtered one North Carolina market strategist. Jim Cramer, the TV stockpicker, nearly melted in a pool of his own sweat on a recent program, saying Bernanke must flood the system with money to stop financial Armageddon. Shouted Cramer: "He has no idea how bad it is out there!"

The Street may be dismayed by Bernanke's sangfroid, but it shouldn't be surprised. This is exactly the kind of policy that Bernanke has spent his entire career arguing for.

What a delightful way to say cold-blooded or cool-headed.
