Well, like Frag said, you already speak English. If I were you, I'd get copies of a few-hundred-year-old books from the library, sit back for a few nights, and develop a better understanding of relatively Old English. Either that, or just read Shakespheare more often. Or perhaps the King James Bible.

On another note, please consider the fact that it is very difficult to get a job with a degree majoring in history... I'm told it is just a bit more useful than majoring in philosophy, which is why I'm only getting a minor degree in it.
