What happened to English?

Chain: Our favourite part of the MSN convo is at the end when you say good bye, because that's the part you say you love us.

Miss Capri: Oh…My…Freakin…Gosh! You - are one sad - I dunno what!

Beth: Another spelling error! I think this is one of my least 'favorite' items you've listed so far. Oh, look! I actually spelled the word right!

and

Chain: We don't want to hear how cool your ex-girlfriend/neighbour/best gal friend is.

Miss Capri: well you're not going to here how cool YOU are, because, you're not. you're such a Mary Sue character.

Beth: Ah-ha! I thought you didn't care what you talked about as long as you talk about something? And that's 'neighbor'! Sheesh, ever heard of spell check? Seriously!

Originally, there was English in Britian. Everyone really knew the jargon. For some reason, however, once America existed, a bunch of words changed; By that, I mean that they're either spelled differently or even uses a completely different word!

(In the example given above) Beth comes upon "favourite", and thinks it's a misspelling; It is not. That is British English.

To be precise about this, any word with "or" becomes "our" for some odd reason in British English (care to explain why?).

First off, here are some of the words that changed.

british = us (reference)

(The letter "Z")
zed = zee
favourite = favorite
colour = color
honour = honor
torch = flashlight (Peppa Pig)
mend = repair (Peppa Pig)
fete = fair (Peppa Pig) (this one's strange)
(Peppa Pig has a few of its own, from different episodes; Any time it mentions fixing something, it really says "mend", torches (really confusing) are really flashlights, and "fete" is a WEIRD one; It looks nothing like English, like they ripped it from another language (we do it all the time; glitch is a word from... What was it? German?))

As you can see, British English has differences, so next time you see favourite, realize it's not a misspelling; It's the way they write (most of the world write like this; America and a few countries only use American English).
