I'm having trouble finding the origin of the terms "curse words" and "swear words" when used as a synonym what many call "bad words" (although I don't agree).
I've found that "curses" when used as an explicative is from the late 19th century, but not much more than that. I'm assuming they have some origin in religion/mysticism/witchcraft due to the earliest meaning I can find of the word "curse," and how "swear" is believed to come from the invocation of the the "sacred" name (Exodus).
Unfortunately, these explanations don't satisfy me. I ask, does anyone have a more detailed explanation with specifics as to the origin of these terms in order to satisfy my curiosity?
