(pronounced sa(n)-FWAH)

The French term from which this developed – sang-froid — literally means “cold blood”. However, when you say that someone acts with “sangfroid” you are not saying they are cold-blooded. You really mean that they have great coolness, steadiness and self-possession under strain.

Example: Despite his nervousness and inexperience, the young designer handled the volatile situation with the developer with professional sangfroid.
