Differences Between
American and British English

Let us see what are the Differences Between American and British English. While there are certainly many varieties of English, American English and British English are the two varieties that are taught in most ESL/EFL programs. Generally, it is agreed that no one version is correct. However, there are certainly preferences in use. The most important rule of thumb is to try to be consistent in your usage. If you decide that you want to use American English spellings then be consistent in your spelling (i.e. The color of the orange is also its flavour - color is American spelling and flavour is British), this is of course not always easy - or possible. The following guide is meant to point out the principal differences between these two varieties of English.

Use of the Present Perfect:

In British English the present perfect is used to express an action that has occurred in the recent past that has an effect on the present moment.

For example:

I've lost my key. Can you help me look for it?

In American English the following is also possible:

I lost my key. Can you help me look for it?

In British English the above would be considered incorrect. However, both forms are generally accepted in standard American English.

Other differences involving the use of the present perfect in British English and simple past in American English include already, just and yet.

British English:

I've just had lunch.
I've already seen that film.
Have you finished your homework yet?

American English:

I just had lunch. (or) I've just had lunch.
I've already seen that film OR I already saw that film.
Have your finished your homework yet? OR Did you finish your homework yet?


Let us see few more Differences Between American and British English. There are two forms to express possession in English.

Have or Have got:
Do you have a car?
Have you got a car?

He hasn't got any friends.
He doesn't have any friends.
She has a beautiful new home.
She's got a beautiful new home.

While both forms are correct (and accepted in both British and American English), have got (have you got, he hasn't got, etc.) is generally the preferred form in British English while most speakers of American English employ the have (do you have, he doesn't have etc.)

The Verb: Get:

The past participle of the verb get is gotten in American English.


He's gotten much better at playing tennis.

British English:

Probably the major differences between British and American English lie in the choice of vocabulary.

Some words mean different things in the two varieties for example:

Mean: (American English - angry, bad humored, British English - not generous, tight fisted)

Rubber: (American English - condom, British English - tool used to erase pencil markings)

If there is a difference in usage, your dictionary will note the different meanings in its definition of the term. Many vocabulary items are also used in one form and not in the other.

One of the best examples of this is the terminology used for automobiles.

American English - hood
British English - bonnet

American English - trunk
British English - boot

American English - truck
British English - lorry

Once again, your dictionary should list whether the term is used in British English or American English.


There are also a few differences in preposition use including the following:

American English - on the weekend
British English - at the weekend

American English - on a team
British English - in a team

American English - please write me soon
British English - please write to me soon

Past Simple/Past Participles:

The following verbs have two acceptable forms of the past simple/past participle in both American and British English, however, the irregular form is generally more common in British English (the first form of the two) and the regular form is more common to American English.

Burn : Burnt OR burned
Dream : dreamt OR dreamed
Leanm : leant OR leaned
Learn : learnt OR learned
Smell : smelt OR smelled
Spell : spelt OR spelled
Spill : spilt OR spilled
Spoil : spoilt OR spoiled


Here are some general differences between British and American spellings:

Words ending in -or (American) -our (British) color, colour, humor, humour, flavor, flavour etc.
Words ending in -ize (American) -ise (British) recognize, recognise, patronize, patronise etc.

The best way to make sure that you are being consistent in your spelling is to use the spell check on your word processor (if you are using the computer of course) and choose which variety of English you would like. As you can see, there are really very few differences between standard British English and standard American English. However, the largest difference is probably that of the choice of vocabulary and pronunciation.
