British English vs American English: 15 Everyday Vocabulary Differences

Ask for a pair of pants in an ordinary London clothes shop and you will be directed towards the underwear. Ask in New York and you will be pointed at the trousers. Same word, same language, completely different result.

That small collision is one of the most reliable ways to spot whether a piece of writing comes from Britain or America. The two varieties share a grammar and most of a vocabulary, but a few hundred everyday words drifted apart — some because American English kept an older British usage that Britain later replaced, others because each country invented its own term for a new object and never agreed to swap back. Neither version is a mistake, and neither is more correct. But if you read widely, write for an international audience, or simply want to be understood on holiday, the pairs are worth learning properly.

Here are fifteen differences that come up again and again, grouped by where you are likely to meet them, with notes on when each word is actually used.

Home and Everyday Objects

Start indoors. A British flat is an American apartment — though the two overlap more than most lists admit. In Britain, "apartment" is not wrong; it usually signals something rented short-term, serviced, or at the smarter end of the market, while "flat" is the plain default. British students share a flat with flatmates; American students share an apartment with roommates. Note that an American roommate need not share your bedroom, just as a British flatmate need not share every room.

The rest of the house behaves similarly. You take a lift in London and an elevator in Chicago. Clothes go into a wardrobe or a closet. Water comes from a tap or a faucet. Rubbish goes in the bin, or in the trash. And when the power fails you reach for a torch in Britain or a flashlight in the US — worth remembering, because an American torch is a burning stick.

Food and Drink

This is where the confusion gets expensive. British chips are thick fried potatoes; American fries are the same thing, while American "chips" are the thin crisp slices that Britain calls crisps. Order chips in a diner in the States and you will get a bag of snacks alongside your sandwich.

A British biscuit covers both the sweet item Americans call a cookie and the savoury cracker — a cheese biscuit is not a dessert. Jam in Britain becomes jelly in the US, while British jelly is the wobbly gelatin dessert that Americans would call Jell-O or simply gelatin. Vegetables differ too: a courgette is a zucchini, an aubergine is an eggplant. If you are carrying food home rather than eating in, Britain offers a takeaway and America offers takeout.

Getting Around

Cars carry the most pairs. The bonnet at the front of a British car is the hood on an American one, and the boot at the back is the trunk. You fill up with petrol or with gas — and in Britain "gas" usually means the fuel piped into houses for heating, so saying you need gas for the car will cause a pause. A lorry is a truck, a motorway is a freeway or highway, and the pavement you walk on is the American sidewalk. In the US, "pavement" generally means the road surface itself.

People queue, or they stand in line. Both phrases are understood on both sides, but only one will sound native in each place. The same goes for the chemist and the drugstore, and for post and mail: you post a letter in Britain and mail it in America.

Clothes and Personal Items

On your feet: trainers in Britain, sneakers in the US. Over your shoulders: a jumper in Britain, a sweater in the US — though in America a jumper is a sleeveless pinafore dress, so the word can raise eyebrows. Legs are the real trap. British trousers are American pants, and British pants are American underwear. If you remember only one item from this list, remember that one.

A British purse is the small wallet you keep notes and coins in; an American purse is the whole bag, which Britain calls a handbag. A baby wears a nappy in Britain and a diaper in the US. Hair can be cut into a fringe or bangs. A mobile phone becomes a cell phone.

Watch Out: Same Word, Different Meaning

These are more dangerous than simple synonyms, because nothing looks wrong on the page. The word exists in both varieties; only the meaning shifts.

• Pants — trousers in the US, underwear in Britain.
• Purse — a handbag in the US, a small wallet in Britain.
• Rubber — an eraser in Britain; in American English the word usually refers to a contraceptive, so ask for an eraser.
• Football — the round-ball game in Britain, the helmeted gridiron game in the US. Americans call the British game soccer, a word Britain coined and then largely abandoned.
• First floor — one level above the street in Britain, where the street level is the ground floor; the street level itself in the US.
• Public school — a fee-paying private school in Britain, a state-funded school in the US. The two meanings sit close to opposite ends of the scale.
• Vest — an undergarment in Britain, a sleeveless outer garment in the US.

Practical Tips for Switching Between Them

1. Choose one variety per piece of writing and stay in it. Mixing "flat" and "apartment" in the same paragraph reads as carelessness, even though both are correct.
2. Set your spellchecker to UK or US English, not both. Most word processors will happily flag colour, realise and organisation as errors if the wrong dictionary is loaded.
3. Reach for the unambiguous word. Writing for a mixed audience? Prefer "
