British vs American English

Quick Answer: British and American English are two standard forms of the same language, and their speakers understand each other easily. The main differences are pronunciation, everyday vocabulary (flat vs apartment), a few spelling patterns (colour vs color) and small grammar habits. Learn either variety and use one spelling system consistently in writing.

Key takeaways

• Spelling: British -our, -re and usually -ise (colour, centre, organise); American -or, -er and -ize (color, center, organize).
• Vocabulary: some everyday words differ completely, such as lift vs elevator, petrol vs gas and queue vs line.
• False friends: pants means underwear in the UK, and chips are fries in the UK but crisps in the US.
• Grammar: British uses "have got" and the present perfect with just, already and yet more often; American says "on the weekend" and "gotten".
• Dates: 10/12/2026 is 10 December in the UK but October 12 in the US, so write the month as a word.
• Exams such as IELTS, TOEFL and Cambridge accept either spelling if you are consistent.

Why are there two main varieties?

English arrived in North America in the 1600s. Over time, both sides of the Atlantic changed in different ways. In the early 1800s, the American lexicographer Noah Webster promoted simpler spellings like "color" and "center" in his dictionaries, and many of these became standard in the US. Today there are also other important varieties, including Australian, Canadian, Indian and South African English.

Spelling differences

Spelling follows clear patterns.

Pattern	British	American
-our vs -or	colour, favour, neighbour	color, favor, neighbor
-re vs -er	centre, theatre, metre	center, theater, meter
-ise vs -ize	organise, realise	organize, realize
-yse vs -yze	analyse, paralyse	analyze, paralyze
double l	travelled, cancelled	traveled, canceled
-ence vs -ense	licence (noun), defence	license, defense
-ogue vs -og	catalogue, dialogue	catalog, dialog (dialogue is also common)
other	programme (TV, plan), tyre, grey	program, tire, gray

Note: British English uses "program" for computer programs. "-ize" is also accepted in British English, and some British publishers use it. But "-ise" is more common in the UK. More spelling patterns are in English spelling rules.

Vocabulary differences

These are the differences you notice most in daily life.

British	American
flat	apartment
lift	elevator
lorry	truck
petrol	gas (gasoline)
motorway	highway, freeway
pavement	sidewalk
underground, tube	subway
holiday	vacation
biscuit	cookie
chips	French fries
crisps	chips
queue	line
mobile phone	cell phone
post	mail
autumn	fall (autumn is also used)
trousers	pants

rubbish, bin	trash, garbage can

Be careful with pants: in British English, pants usually means underwear. And chips means different foods on each side of the Atlantic.

Grammar differences

Grammar differences are small, but you will notice a few.

Present perfect vs past simple

British English uses the present perfect more often with "just", "already" and "yet".

• British: "I've just eaten." "Have you finished yet?"
• American: "I just ate." "Did you finish yet?" (The present perfect is also correct in American English.)

Have got vs have

• British: "I've got a car." "Have you got a pen?"
• American: "I have a car." "Do you have a pen?"

Collective nouns

• British: "The team are playing well." (plural is common)
• American: "The team is playing well."

Prepositions

British	American
at the weekend	on the weekend
in a team	on a team
different from or to	different from or than
Monday to Friday	Monday through Friday

Past forms

Some verbs have different past forms:

• British: learnt, dreamt, spelt (learned and dreamed are also common)
• American: learned, dreamed, spelled
• British "got" vs American "gotten": "She's gotten better" is American; British uses "She's got better."

Pronunciation differences

Pronunciation is the biggest difference you hear.

• The r sound: most American speakers pronounce r after vowels ("car", "hard"). Standard Southern British English usually does not.
• The t sound: in American English, t between vowels often sounds like a quick d: "water", "better".
• The a in words like "bath", "dance", "can't": standard Southern British uses a long ⁄ɑː⁄ sound; American uses ⁄æ⁄.
• The o in "hot", "stop": American uses a more open ⁄ɑ⁄, British uses ⁄ɒ⁄.
• Word stress: a few words differ, like "advertisement" (British stress on "ver", American often on "tise") and "garage" (British GA-rage, American ga-RAGE).

Both countries have many regional accents, so these are general patterns, not rules for every speaker. For practical tips, see English pronunciation tips.

Dates and numbers

• British: 12 October 2026, written 12/10/2026.
• American: October 12, 2026, written 10/12/2026.

This can cause real confusion. In international emails, write the month as a word.

Which should you learn?

Choose based on your life:

• Living or working with Americans, or watching mostly US shows? Choose American.
• Living in the UK or Europe, or preparing for Cambridge exams? British may feel natural.
• No preference? Choose the variety your course uses, and listen to both.

Exams such as IELTS, TOEFL and Cambridge accept both spellings, as long as you are consistent. LearnLingo uses American spelling by default and mentions British variants where they matter. For American phrases, see American English expressions.
