Hello there!
The way how British and American vocabulary is different because first of all they use an accent to speak. Also they pronounce several words differentially.
Example:
We say the but Britsh people say the with a long a so its like thee.
This is how American and British vocabulary and usage is different.
Hope this helps ;)
