[Nimbus117]

The English language is a fairly recent one and is a mixture of several languages after many invasions as well as colonisations (note there is no 'z' in this word).

I think that you will find that 'colour' was originally spelt this way, the original occupants of the US had a completely different word for when they were discussing things in their wigwams.

The immigrants who occupy the country now didn't know how to spell and forgot to take a dictionary hence 'color' and a heap more incorrectly spelt words.
