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.
3. A woman who is a doyen.
A woman who is a doyen? How come they don't include "a man who is a doyen"?
I think definition number three is actually from "doyenne", although that begs the question for why there needs to be a separate word for a male doyen and a female doyenne.
