I got through high school English classes by reading heavily during summer, then turning in 30-40 book reports during the year. Read many British Manners novels, in which such words were common. So I know the word, but have used it maybe 3-4 times in my life, despite having been a writer (non fiction) for decades. It's a great word and has some real political possibilities these days.
Back to the topic. If you were going to be starting anew, which 10 bits would you want in your collection?
Maybe I'll start a new topic for a survey to help this project along...
The more I do, the less I accomplish.
