You read carefully and you may find that the American English spellings are in a way simpler - it keeps the sound but has removed some "useless " letters, e.g. both "vour " and "vor " sound the same. So the Americans use "color ", "favorite " and "labor ".

Similarly, American use "ter " because it is a lot more common than "tre ". There are a lot of words ending that way, e.g. painter, writer or even water. So naturally "centre " was mis-spelt "center ".

To tell the truth, many Americans do not care spelling at all. They just make up the spelling to fit in the sound.

因為唔同國家有唔同串法。
