Defenestration is the action of throwing something, especially a person, out of a window. The word comes from the Latin de- (down or away from) and fenestra (window or opening).

History of the word
The word comes from two events in history, which both took place in Prague. In 1419, seven town officials were thrown from the Town Hall, starting the Hussite War. In 1618, two Imperial governors and their secretary were thrown from Prague Castle, which started the Thirty Years War. These two event, particularly in 1618, were called the Defenestration of Prague and gave rise to the word and the idea.
