My current teacher for this subject gave us a funny quote the other day. I don't remember who said it, but it went like this:
The english language is like a theif in the night, that robs other languages in dark alleys, riffling their pockets for words.
Given how our language is based in Germanic, with latin and greek playing for second, and us stealing words from french and other languages, it is a fair quote.
Not that we like to think of it that way....
