Cancelled and canceled are both correct spellings. Canceled (one l) is the standard American spelling; cancelled (two ls) is the British spelling, also used in Canada, Australia, New Zealand and Ireland. The noun cancellation has two ls in both. The same split applies to canceling (US) and cancelling (UK).
The difference comes from a wider rule about verbs ending in -l, so the same choice appears in traveled/travelled, labeled/labelled, modeled/modelled, fueled/fuelled and signaled/signalled. The 30 questions below cover cancel first, then the whole -l family, then the consistency traps that show up in real business writing. Each question names the variety of English, so only one answer is correct.

Answer key and explanationsOpen after you finish the quiz.
- 1. canceledStandard American spelling uses one l: canceled. AP style uses canceled, and Merriam-Webster lists it first. Cancelled is the British form.
- 2. cancelledBritish English doubles the final l of cancel before -ed, so the UK spelling is cancelled. Canceled with one l is the American form.
- 3. cancelingThe -ing form follows the same pattern as the past tense. American English keeps one l: canceling. British English writes cancelling.
- 4. cancellingBritish English doubles the l before -ing as well as before -ed: cancel, cancelled, cancelling. Canseling is not a spelling in any variety.
- 5. cancellationEven American style keeps two ls in the noun: cancellation. AP style pairs canceled and canceling with cancellation. The one-l form cancelation is rare and is not AP style.
- 6. cancellationCancellation has two ls in British English, just as cancelled does. This is the one form of the word that US and UK style share.
- 7. Both are correct; the choice depends on US or UK styleBoth spellings are correct. The difference is regional: canceled is American, cancelled is British and Commonwealth. Both cover the past tense and the past participle.
- 8. cancelledAustralian English follows British spelling here: cancelled, cancelling. New Zealand and Irish English do the same.
- 9. canceledOrder confirmations and app notices written for American users use canceled with one l. Cancelld drops the vowel and is never correct.
- 10. cancelledCanadian spelling generally follows British practice for this word: cancelled and cancelling, with two ls. Canceled with one l is American style.
- 11. traveledTravel is stressed on the first syllable (TRAV-el), so American English does not double the l: traveled, traveling, traveler.
- 12. travelledBritish English doubles a final l after a single vowel whatever the stress, so travel becomes travelled, travelling and traveller.
- 13. labeledLabel is stressed on the first syllable, so American English writes labeled and labeling with one l. Labelled is the British form.
- 14. labelledBritish English doubles the l: labelled, labelling. This is the same pattern as cancelled and travelled.
- 15. modeledModel is stressed on the first syllable (MOD-el), so the American forms are modeled and modeling. British English writes modelled and modelling.
- 16. FuelledBritish English doubles the l in fuelled and fuelling. American English writes fueled and fueling. Note that rumours also marks this sentence as British.
- 17. signaledSignal is stressed on the first syllable, so American English writes signaled and signaling with one l. British English uses signalled.
- 18. controlledControl is stressed on the last syllable (con-TROL), so American English doubles the l too: controlled. Controled is wrong in every variety.
- 19. excelledExcel is stressed on the last syllable (ex-CEL), so both American and British English write excelled. The US one-l rule applies only when the stress is not on the last syllable.
- 20. counselorThe doubling rule also covers -er and -or nouns. The usual American spelling is counselor; British English writes counsellor.
- 21. jewellerBritish English doubles the l before -er: jeweller, just as it writes traveller. American English uses jeweler.
- 22. marvelousThe doubling difference also appears before -ous. American English writes marvelous with one l; British English writes marvellous.
- 23. The canceled order needs a cancellation number.US style is canceled (one l) plus cancellation (two ls). Mixing the two counts is not inconsistent; it is the standard American pattern. The second option is consistent British spelling.
- 24. We travelled to the venue, but the event had been cancelled.British English doubles the l in both verbs: travelled and cancelled. The mixed options combine a US form with a UK form, which looks careless in one sentence.
- 25. fulfilSome words go the other way: British English writes the base form fulfil with one l, and American English writes fulfill. Both write fulfilled and fulfilling, because the stress falls on the last syllable.
- 26. installmentsInstallment is another reverse case: American English writes installment with two ls, while British English writes instalment with one.
- 27. enrolledEnroll is stressed on the last syllable, so American and British English both write enrolled. The base form differs: enroll in the US, enrol in the UK.
- 28. dialedDial follows the US one-l pattern: dialed, dialing. British English writes dialled and dialling.
- 29. Pick one variety, record it in a style guide, and apply it consistentlyReaders accept either variety, but switching within one document looks like an error. Choosing one variety and writing it down keeps every author and every document aligned.
- 30. cancellationCancellation has two ls in American and British English alike. Traveling, canceling and labeling are the one-l American forms of verbs stressed on the first syllable.
The Rule: One L in US English, Two in UK English
Cancel ends in a single vowel plus l, and the two main spelling traditions treat that ending differently. American English keeps one l when adding -ed or -ing to cancel; British English doubles it. Neither is a mistake, and neither is more correct than the other. They belong to different style traditions.
American dictionaries do record cancelled as a variant, so you will see it in American writing too. But American style guides such as AP use canceled, and that is the form most US readers expect in news, product and business writing.
- US English: cancel, canceled, canceling, cancellation.
- UK, Irish, Australian, New Zealand English: cancel, cancelled, cancelling, cancellation.
- Canadian English: usually cancelled and cancelling, in line with British practice.
- Everywhere: cancellation with two ls.
Cancellation is the fixed point. If you write canceled, keep cancellation with two ls; that combination is standard American style, not a mix-up.
The Wider -L Doubling Rule
Cancel is one member of a large family. British English doubles a final l after a single vowel before a suffix that begins with a vowel (-ed, -ing, -er, -ous), whichever syllable is stressed. American English doubles it only when the stress falls on the final syllable.
That explains why the US/UK difference appears in travel, label, model, fuel and signal (all stressed on the first syllable) but not in control, compel, excel, propel or rebel (stressed on the last syllable). Both varieties write controlled, compelled and excelled.
- travel: traveled, traveling, traveler (US) / travelled, travelling, traveller (UK).
- label: labeled, labeling (US) / labelled, labelling (UK).
- model: modeled, modeling (US) / modelled, modelling (UK).
- fuel: fueled, fueling (US) / fuelled, fuelling (UK).
- signal: signaled, signaling (US) / signalled, signalling (UK).
- Stressed on the last syllable, both varieties double: controlled, compelled, excelled, propelled, rebelled.
The Words That Go the Other Way
A handful of words have the extra l on the American side. American English writes fulfill, enroll, skillful, installment and instill; British English writes fulfil, enrol, skilful, instalment and instil. When a suffix is added to the verbs, both varieties usually converge again: fulfilled, enrolled, instilled.
These reverse cases are why a single rule like 'British English always has more ls' does not work. It is more reliable to learn the cancel/travel family as one pattern and the fulfil/enrol group as a short list of exceptions.
Which Spelling to Use in Business Email
If your organization has a style guide, follow it. If it does not, choose the variety that matches your company's base or your main audience, and use it everywhere: emails, help-center articles, invoices and product messages. International readers rarely object to either spelling; what looks unprofessional is a message that says canceled in one line and cancelled in the next.
Set your editor's language to English (United States) or English (United Kingdom) so the spellchecker enforces the same choice, and agree on how to treat quotations and proper names, which keep their original spelling.
- One variety per document, and ideally per organization.
- Write the decision down: 'We use US spelling: canceled, traveled, labeled.'
- Do not change the spelling inside quotes or official names.
Before sending, search the document for 'cancel' and 'travel'. If both canceled and cancelled appear, pick one and fix the rest.

Frequently Asked Questions
Is it cancelled or canceled in American English?
Canceled, with one l, is the standard American spelling and the form AP style uses. American dictionaries also list cancelled as a variant, but most US publications and companies use canceled, canceling and cancellation.
Why does cancellation have two Ls in American English?
Cancellation is spelled with two ls in both American and British English. The American one-l rule applies to the inflected verb forms canceled and canceling, not to the noun, so canceled plus cancellation is the normal US pattern.
Should I use cancelled or canceled for an international audience?
Either is acceptable. Choose the variety your organization uses, or the one that fits your main readers, and apply it consistently across the email or document. Consistency matters more than which variety you pick.
