From Wikipedia:
Defenestration is the act of throwing someone or something out of a window.[1] The term "defenestration" was coined around the time of an incident in Prague Castle in the year 1618. The word comes from the Latin de- (from) and fenestra (window or opening).[2]
The act carries the connotation of forcibly or peremptorily removing an adversary, and is sometimes used in just that sense;[3] it also suggests breaking the windows in the process (de- also means removal). Although defenestrations can be fatal due to the height of the window through which a person is thrown or throws oneself, or due to lacerations from broken glass, the act of defenestration need not carry the intent or result of death.
