The term 'apoplectic' is related to which of the following?

The term 'apoplectic' is primarily associated with a state of intense anger or rage. It originates from the Greek word that indicates a seizure or a sudden burst, which metaphorically relates to the overwhelming emotions that can accompany extreme anger. When someone is described as apoplectic, it often conveys that they are so furious that they are almost immobilized by their emotional response, to the point that it can appear as if they are about to explode with rage. This connection to anger distinguishes it from other emotional states like confusion, joy, or fatigue, which have different implications and would not encapsulate the intensity described by 'apoplectic.'
