First of all, I did not know that a palace and castle were the same thing. They aren't, according to this random dictionary. A castle is a place someone builds to protect himself when he's trying to conquer a foreign land. A palace is just a fancy place that doesn't necessarily have any special function of defense (although most politically important buildings in history have required defense).
Rob, I don't mind the French taking our language and distorting it. Actually, it's the French in English that bothers me in a way... because all these evil teachers know French words that I don't, when I'm the one who's supposed to know French! Hahaha... But knowing French really helps me on tests and stuff.
I had never seen fête in English until I took a test, so my studies helped me there... But now I see that word in English constantly.
Well, since French mainly entered the English language through the upperclass/government, it's not surprising that the 100 most basic words are of Germanic origin. If one could even get the important people to change their most basic speech, then how would they get the commoners to change theirs?
You notice how when you read poetry in Old-Middle English, it gets suddenly more like now once it reaches the stage where French words come in. Many of those words may have reached poetry and the upperclass as a whole, but it looks like the common folk won this war.
I guess that's the only reason there's a big difference between written and spoken language...... because written language began as separate from the common tongue and people.
