British English is the form of English used in the United Kingdom. It includes all English dialects used in the UK;

American English is the form of English used in the United States. It includes all English dialects used in the US.

Between the various differences there are lexical differences: sometimes there are words that means the same concept, sometimes, instead, there are words that means different things, for example:

British English

American English


Autumn Fall Autunno
Ground Floor First Floor Pianterreno
Holiday Vacation Vacanza
Lift Elevator Ascensore

There are cases when the British English requieres the use of present perfect but American English use past simple:

BrE: He’s just gone home;

AmE: He just went home.

“Have got” (BrE) vs. “Have” (AmE)

To indicate have/possession English people use “have got”, while in American English it’s more frequent “have”:

BrE: Have you got a laptop?;

AmE: Do you have a laptop?

Got” (BrE) vs. “gotten” (AmE)

In American English the past participle of “get” becomes “gotten”, while in British English is “got”:

BrE: I’ve never really got to know him;

AmE: I’ve never really gotten to know him.

The use of subjunctive is more common in American English:

BrE: It’s essential that they should be warned;

AmE: It’s essential that they be warned.

 In American English the letter -L in unstressed syllable followed by ending, don’t doubles:

AmE: traveler, leveling;

BrE: traveller, levelling.

Some words that in British English finish in -tre, -our, -ogue, -ise, in American English finish in -ter, -or, -og, -ize:

BrE: centre, colour, catalogue, realise;

AmE: center, color, catalog, realize.
