Try telling that to a spell checker!
There are several right and wrong spellings in English - they are just country dependent. Correct spelling in Britain is not the same as in America. Canada uses some US and some UK spellings, just to make things complicated (and the so-called Canadian spell checker from Mozilla is just a relabelled UK spell checker that is just plain wrong for some words. No doubt a bright idea from some yank or brit who didn't know there was a difference.)
