Curse words often get confused with profanity. A ‘curse’ word is a form of taking an ‘oath’ or calling down something bad. For instance ‘ If I am lying, let me trip over a rock’ is an example of swearing, which is an example of an original curse. I suppose you would like to know where did profane language come from. Profanity came about to be language used to stand out from regular speech in order to make a profound point.
