Defenestration is a rare word, yet a lot of people know it. It often appears on lists of 'favourite words' or even 'words most searched for on Google'. There's something about the word that captures the imagination. It's probably the meaning. It means 'the act of throwing out of a window'.
The most famous defenestration in history was the Defenestration of Prague in 1618, when Bohemian insurgents threw a couple of Imperial officials out of an upper-storey window. The event was a catalyst of the Thirty Years' War.
Interestingly, the word 'defenestration' was used in a Financial Times headline today: F&C Defenestrations Good for Governance. The article used 'defenestration' as a synonym of 'booting out' or 'sacking'.
