How American English broke away — and which half actually moved

Received Pronunciation is younger than the United States.

That single fact reorganises the whole subject. The standard account of American English treats Britain as the fixed point and America as the deviation — the original on one side of the Atlantic, the corruption on the other. The history does not support it. English left England in the seventeenth century, and both halves went on changing. On several of the most audible differences, it was Britain that moved.

1. The retentions

The letter R. An American says the r in car, farm, water. Standard southern British English does not. The non-rhotic accent is the innovation: r-dropping took hold in south-eastern England in the late eighteenth century and spread through the nineteenth, well after the colonists had sailed. They took a rhotic English across the Atlantic and kept it. England changed behind them.

The exceptions prove the mechanism. The two American regions that went non-rhotic — coastal New England and the coastal South — are precisely the two that kept the closest commercial and social contact with London. The prestige feature travelled by ship, and it only reached the ports.

The flat A. British bath, dance, path, can't, laugh with a long ah is another innovation of around 1800 in southern England. Americans kept the older short a, and so did most of northern England — a Mancunian and a Chicagoan agree about bath against London.

The vocabulary. A good deal of what the British have spent two centuries calling Americanisms is simply seventeenth-century English that Britain later dropped.

So the American who says I guess I'll take the fall semester is using three constructions that were unremarkable in London before anyone thought of leaving it.

This should not be pushed too far. The folklore that Appalachian speech is "preserved Elizabethan English" is untrue — every American variety has changed enormously in four hundred years, and some, like the Northern Cities vowel shift around the Great Lakes, are changing right now. The accurate claim is narrower and more interesting: on specific well-documented features, the American form is the conservative one.

2. Noah Webster, who did it on purpose

Everything above happened by drift. What follows was policy.

Noah Webster was a Connecticut schoolteacher who believed, with total sincerity, that political independence was incomplete without linguistic independence. "A national language," he wrote, "is a band of national union." He set out to give the republic its own spelling, and he had the distribution to do it: his 1783 Grammatical Institute of the English Language, universally known as the Blue-Backed Speller, sold in the tens of millions and taught American children to read for the better part of a century. His American Dictionary of the English Language followed in 1828 with 70,000 entries, some twelve thousand of which had never appeared in a dictionary before.

The reforms that stuck are the ones you know:

The reforms that did not stick are better. Webster genuinely proposed, and in places printed, tung for tongue, wimmen for women, iland for island, ake, soop, masheen, thum, bild, croud, definit, examin. He was right about nearly all of them on phonetic grounds — island really did acquire its s by a Renaissance error — and it made no difference whatsoever. Spelling reform succeeds only where it is invisible; a nation will drop a u without noticing and will not be told how to spell women.

The nuance usually left out: Webster did not invent most of what he standardised. Color and honor were live variants in England before he was born. What fixed the -our forms as British was Samuel Johnson's dictionary of 1755, which chose the French-influenced spellings on etymological grounds. Two lexicographers, seventy-three years apart, made opposite calls on the same words, and each had a nation reading over his shoulder. Most of the transatlantic spelling divide is the residue of that disagreement.

The -ise / -ize split is the one everybody gets wrong. -ize is not an Americanism. It reflects the Greek -izein and is the house style of Oxford University Press to this day. British -ise is the French-influenced habit that spread later. On this point America is again the conservative party, which surprises everyone who has ever been corrected about it.

3. What the continent supplied

A language arriving in an unfamiliar place needs words for what it finds there, and American English took them from whoever was to hand.

Indigenous languages, mostly Algonquian, supplied the landscape and its animals: moose, raccoon, skunk, opossum, chipmunk, hickory, squash, persimmon, moccasin, toboggan, caucus, bayou. There was no English word for a moose, because there was no moose.

Dutch, from the New Netherland colony that became New York, supplied a surprisingly domestic set: cookie (koekje), coleslaw (koolsla), waffle, stoop, cruller, snoop, spook, dope, and Santa Claus from Sinterklaas. It also supplied boss, from baas. That word did specific work: it gave a republic that was still holding people in slavery a way to name an employer without using the word master.

German, through the enormous nineteenth-century migration, gave delicatessen, kindergarten, pretzel, noodle, semester, seminar, hamburger, frankfurter, spiel, kaputt — and, in the upper Midwest, the sentence pattern are you coming with?

Spanish, through the Southwest and the cattle economy, gave the entire vocabulary of the western: ranch, corral, lasso, stampede, rodeo, canyon, mesa, plaza, patio, vigilante, bonanza, cafeteria, tornado, alligator (from el lagarto, the lizard).

West African languages, carried by enslaved speakers and transmitted through Gullah and other creoles, gave goober, gumbo, okra, yam, banjo, juke (surviving in jukebox), and probably tote. The etymologies here are less securely documented than the others, for reasons that have nothing to do with linguistics: the speakers were not the ones writing dictionaries.

Yiddish arrived late, through New York, and went further than any of them. Schmooze, klutz, schlep, kvetch, nosh, maven, chutzpah, bagel — and glitch, which went from Yiddish glitsh, a slip, into New York speech, then into NASA jargon in the 1960s, and from there into the vocabulary of every software engineer on earth.

4. Coining, and the British reaction

New institutions needed new words, and Americans made them freely: congressional, presidential, sidewalk, bookstore, railroad, elevator, apartment, baggage, gasoline, truck, movie. John Witherspoon coined the term Americanism itself in 1781, modelling it on Scotticism, and he did not intend it as a compliment.

British literary opinion was appalled, and the record of its complaints is now comedy. Thomas Jefferson's belittle was denounced by London reviewers as a barbarism. Coleridge objected to talented. Lengthy, demoralize, influential and reliable were each attacked in print as ugly transatlantic inventions. All of them are now unremarkable in British English, and reliable has been used by every British newspaper that has ever run a piece complaining about Americanisms.

The complaint tradition survives intact and is still mostly wrong. The British objection to can I get a coffee, train station, deplane and heads-up is a genuine reaction to genuine imports. The objection to fall, gotten, trash and I guess is a nation objecting to its own discarded property.

5. Where they actually differ, for teaching purposes

Vocabulary is the visible layer and the least troublesome, because context usually rescues the learner:

The pair worth flagging in class is pants: trousers in America, underwear in Britain. It is the one that produces an actual misunderstanding rather than a pause.

Grammar differences are fewer and more likely to be marked wrong in an exam:

• gotten as past participle (US) against got (UK) — he's gotten better / he's got better
• collective nouns: the team is playing (US) against the team are playing (UK)
• do you have (US) against have you got (UK)
• on the weekend (US) against at the weekend (UK)
• in the hospital (US) against in hospital (UK)
• write me (US) against write to me (UK)
• learned / dreamed / burned (US) against learnt / dreamt / burnt (UK)
• dates: September 11 against 11 September, and the numeric forms that follow from it

Punctuation quietly follows: American double quotation marks and commas inside the closing quote, British singles and commas outside; Mr. and Dr. with a full stop in America, without in Britain.

6. The current is now flowing the other way

Since 1945 the export direction has reversed. American English carries the film industry, the music industry, the software industry and the vocabulary of business, and British English absorbs it continuously — movie, guy, cool, okay, hi, awesome, reach out, going forward. The traffic is not symmetrical and has not been for eighty years.

For a learner this is the practical situation: the two varieties are both fully standard, mutually intelligible in essentially all registers, and unevenly distributed across the sources a student will actually meet. European classrooms still lean British; the internet, the streaming service and the workplace lean American. The workable rule is to produce one variety consistently and understand both. Mixing them is what reads as an error — colour and center in the same paragraph looks like carelessness in a way that either alone never does.

Four hundred years ago the same language went in two directions. One half kept its R, its flat A and its fall, and lost its -u-. The other half kept its -u- and lost the rest. Neither is the original, because there is no longer anywhere the original is spoken.
