savoir faire

sav-wah FAIR´

(French, ‘know-how’)

Savoir faire is the ability to act correctly
and confidently in any social situation. Those who possess
savoir faire have worldly experience and a polished confidence
in their behavior.

Most English dictionaries spell savoir faire as two separate
words, but for a little added snobbery, spell it the French way,
with a hyphen (savoir-faire).
