Semantic Crisis Intervention

Some people are bothered by changes in a word’s meaning (see: literally), while others have a more relaxed attitude towards semantic drift. For those who feel vexed when a word seems to have suddenly changed its spots, it may be of some comfort to know that words in English do this all the time; crisis is a fine example. Originally, crisis denoted “the turning point for better or worse in an acute disease or fever.” Now it most commonly means “a difficult or dangerous situation that needs serious attention,” yet few people insist that it should be used exclusively in its older meaning. The normality of semantic change can be seen in another word that first appeared in febrile contexts: hectic, which now is primarily used to mean “very busy,” originally referred to a fever that was fluctuating but recurrent.
