Hermitage (noun): "A secluded place, a hideaway."

Heard: Jonathan Harris used the word in a talk he gave at TED which I listened to this morning. I'd been hearing it my whole life and never knew what it meant until I looked it up today.

Also: A world famous art museum in Russia (and location of the longest unbroken shot in the history of cinema, 90 minutes in the 2002 movie Russian Ark), a fancy hotel in Nashville, TN, and a little street right near the house where I grew up.
