Well, to be honest, we cannot relate the accent to the language. But what really confuses me is:

1. "wh" usage. wonder for example why to write "what" and pronounce it "hwat", write "who" and pronounce "ho"

2. Mixing between "s" and "z" and the confusion it is making between British and American English. Like "organise" and "organize"

3. silent "gh" wonder why should it be there.

That's what I remember now
