How do you say plume in french?

Plume is pronounced "plewm". When pronouncing the French u, stick your lips out a little bit and try to make the sound very tight and at the front of your mouth. It's actually the same as the i vowel (as in ski) but with a rounded mouth shape rather than a smiling one.

(plume is French for feather; the English Word plume is panache in French.)
