American English 和 British English 的差別在哪裡？如果不好說明，請提供一些例句。

Although the core of our languages is the same (American English stemmed from British English), American English now has a much more diverse vocabulary, use of slang, and lack of spoken grammar.

British English also uses outdated words, spells things with extra letters, and sometimes pronounces letters that aren't there.

Both have their ups and downs, but both are good to be familiar with if you want to be fluent in English.
