I wrote this project for a class during my freshman year of college (Spring 2002), and thought that it was a very interesting thing to research. It is not as comprehensive as I should like, but it is still quite good, and certainly gives an interesting twist on things. Etymology is probably the most intriguing thing in the field of linguistics for me, so papers that explain it tend to appeal greatly to me, I hope you find this as interesting as I do.
