So, as a result of the interesting discussion that emerged on the post below, I did a little more looking around on ye worlde wide webbe and came across some great sites.
First, I found an outstanding (and quite comprehensive) glossary of swears in fantasy and sci-fi from cuparius.com. Next, an interesting post on the subject by Jo Walton. Also, check out a great post by Joe Abecrombie (who uses many, many curses in his novels). Finally, a list of all the slang and invented curses used in Jordan’s WOT.
What do you see in here that works? What’s not so great?
