Word Power and Serendipity

The other night I am lying in bed and i am wondering to myself, “I wonder what doyenne means.”.
Seriously, I was.
It’s a good word, fills your mouth and rolls around on your tongue, even when you say it in your head. Doyenne.
So, I get the Word of the Day email this morning and there it is, the definition for the word doyenne:
doyen \DOY-en; DWAH-yan\, noun:
1. The senior member of a body or group.
2. One who is knowledgeable or uniquely skilled as a result of long experience in some field of endeavor.
doyenne \doy-(Y)EN; dwah-YEN\, noun:
A woman who is a doyen.
Wow! Really. Now i can move on to my newest word related quest, finding the single word that encompasses “under the pseudo-calm I’m seething and ready to punch”. Perhaps something that would indicate a hidden, but tightly coiled anger.
