Ok

That clarifies a lot. However even in the Netherlands lots of words are derived from French words and even German and English. I think we're probably the country (besides English speaking countries) that uses the most English words in it's language. Espescially modern words are very often derived from English. That's in fact is also the main reason why I am suprised that call center from which I presumed was an English (American) word is in fact an English word with centre spelled as a French (enlish) word. I knew this was the case with centre, however I expected the word call center to be an American English word....thus spelled center. As far as I know the American way for spelling centre is center. (you see I write with great precaution now ;-)).
So I assumed center to be the right spelling
