Learning the differences between American English and British English.


The impact of British English on American English & vice versa

Languages are undergoing a neverending evolution. They never stay exactly the same. If you take a closer look at the English language, you’ll see that the way people spoke in the 1800s and the way people speak now has changed significantly.

But languages aren’t only affected by the passing of time. They’re also affected by historical events, such as colonization and war, immigration, gentrification, and the proximity to neighboring countries. And because so many different factors affect how languages evolve, it’s often hard to pinpoint the exact reasons behind specific changes.

That’s precisely what’s going on with British and American English. The common belief is that British English is the “original” English, and American English is a changed, adapted version. However, that’s not entirely accurate.

While English was brought to America by the British during colonization, British English has also incorporated many words and expressions from American English. The linguistic exchange between the two variants is more nuanced than a simple one-way influence.

British English vs American English pronunciation

Oh, don't we all just love Hugh Grant's British accent in Notting Hill or Jude Law’s accent in The Holiday?

British and American English can sometimes sound like they're two different languages, and that's because of the way words are pronounced. There are many differences between British and American English pronunciation, but it goes deeper than just the two countries.

For instance, in the UK, you've got a whole range of different accents, from the posh London one to the barely understandable for most people Scottish, Irish, and Welsh.

The US also has quite a few regional accents. For instance, New Yorkers speak with a distinctive accent, but the Texans have a twangy accent you probably know from movies like Sweet Home Alabama.

Differences in grammar between British and American English

How many times have you wondered whether your brain is playing tricks on you when you come across words like “learnt” instead of “learned” or “gotten” instead of “got”?

In those instances, you probably thought, “do I remember this wrong?” The answer is no, you don’t. It’s just that you probably didn’t know that there are many differences in the grammar and usage between British and American English until now.

Differences in grammar between British and American English.

Use of present perfect tense

In British English, the present perfect tense is used to emphasize the recent or repeated completion of an action with a connection to the present moment. In American English, we can also use the present perfect to convey this, but we’d rather use the simple past tense if we consider the action finished.

For example:

  1. I have just finished my homework. (British English)
    I just finished my homework. (American English)
  2. She has already eaten lunch. (British English)
    She already ate lunch. (American English)
  3. They have visited Paris multiple times. (British English)
    They visited Paris multiple times. (American English)

Collective nouns and verb agreement

In American English, collective nouns such as team, band, and herd are treated as singular nouns, while in British English, they’re more commonly treated as plurals, although both forms are correct.

For example:

  1. The team are playing well. (British English)
    The team is playing well. (American English)
  2. The band have released a new album. (British English)
    The band has released a new album. (American English)
  3. The staff are on a break. (British English)
    The staff is on a break. (American English)
  4. The government are announcing a new policy. (British English)
    The government is announcing a new policy. (American English)

Past forms and past participles of verbs

Have you ever racked your brain trying to figure out whether you should spell “learned” or “learnt” in a sentence? Both versions are correct, and you’ve probably seen both in written texts. So, what’s the difference?

As you probably guessed, one is used in American English (learned) and the other in British English (learnt). Aside from this particular example, there are other common past forms with different endings in British vs American English, such as:

  1. She dreamt of a better future. (British English)
    She dreamed of a better future. (American English)
  2. He’s got a new car for himself. (British English)
    He’s gotten a new car for himself. (American English)
  3. I spilt coffee on my shirt. (British English)
    I spilled coffee on my shirt. (American English)
  4. They knelt down to pray. (British English)
    They kneeled down to pray. (American English)
  5. The plane smelt of fuel. (British English)
    The plane smelled of fuel. (American English)


Will Americans understand you if you speak British English and vice versa?

The short answer is yes. After all, you speak the same language with some nuanced differences that rarely affect communication.

Typically, British people understand and know more American words and slang than American people do British words. That’s because British people tend to watch more American movies and TV shows than American people watch British ones. So, if you speak American English while on vacation in the UK, people will likely understand everything you say.

However, if you speak British English on your trip to the US, you may get questions like “What was that?” or “Can you repeat?” if you use a specific British word people don’t usually hear.

Funny differences between British vs American English

Sometimes, the differences in vocabulary between British English and American English can not only be confusing but also quite funny. Here are some of the funniest ones we could think of.

1. Dummy vs. Pacifier

Did you know that in the UK, babies suck on a dummy? For Americans, that can be pretty confusing because they’ll mentally picture a plastic human (you know, like the ones you see in the store displays wearing clothes). In American English, a dummy also means a person who is not very smart. And babies in America suck on a pacifier.

2. Pants vs. Trousers

If you ever ask a British person whether you should wear pants to go out, you’ll find a perplexed look on their face. “Of course, you should wear pants!” they’ll shout in disbelief. What you meant was whether you should wear trousers, and what they understood was underwear.

Yes, pants in British English means underwear, and pants in American English means trousers.

3. Toilet vs. Bathroom

If you ask an American waiter where the toilet is, you may hear “in the bathroom.” And if you ask a British waiter where the bathroom is, you may find a confused look on their face, wondering whether you intend to take a bath before dinner.

A toilet in the US means the literal “throne” you sit on in the bathroom. A bathroom in the UK is more associated with a literal bath or shower. So, make sure to ask for the “toilet” in the UK and the “bathroom” in the US.
