Because few if any people know it
The term was coined around the time of an incident in Prague Castle in the year 1618. The word comes from the Latin de- (out of or away from) and fenestra (window or opening). Likewise, it can also refer to the condition of being thrown out of a window, as in “The Defenestration of Ermintrude Inch“.
While the act of defenestration connotes the forcible or peremptory removal of an adversary, and the term is sometimes used in just that sense, it also suggests breaking the windows in the process (de- also means removal). Although defenestrations can be fatal depending on 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 of, or result in, death.
I came across this word years ago and have yet to use it in a story even tho I really want to.
tell me some of the words or phrases you want to use and have not found the right situation
