Quote from NikolaiSummersWell, you also have to understand that some of these 'bad' words have very different meanings as to where they come from. Like the f-word, that was used to describe when a priest is being removed from his holy duties. In today's times, we use that word to describe someone who has been beaten up or killed, etc. I found that out myself, I don't know if that is correct.
That is not even remotely accurate; fuck never had a religious connotation at all. Even in Old English from the manuscripts it survived in (which were not very numerous considering it was an extremely taboo word) it had a sexual connotation.
