Apoplexy is a noun that refers to a state of intense, uncontrollable rage.
The Greek word apoplēssein (ap oh play SANE) means ‘to cripple by a stroke.’ In time, it evolved into apoplexy, which maintained its original meaning. But the word can also be used outside of medical contexts to refer to a state of extreme anger, especially if this state makes you unable to speak. For example.
When I first called the police to report I’d been scammed out of all of my money, I couldn’t even answer the police officer’s questions. The apoplexy I’d found myself in made it impossible for me to speak.
