The correct spelling is "cancelled" with two L's

In American English, the word is spelled canceled with one L. In British English, Australian English, and Canadian English, it is spelled cancelled with two L's. Both are correct — the difference comes down to which English-speaking country's standard you follow. If you are writing for a US audience or using American spell-check, one L is standard. If you are writing for the UK, Australia, Canada, or using those regions' spell-check settings, two L's is standard.

The reason for this difference is a rule about doubling consonants. When you add a suffix like "-ed" or "-ing" to a word that ends in a consonant, you sometimes double that final consonant before adding the suffix. American English tends to keep the single consonant, while British English tends to double it. The word "cancel" follows this pattern: British writers double the L to get "cancelled," while American writers keep it single to get "canceled."

Key Takeaways

  • American English spells it "canceled" with one L, and this is what most US spell-checkers expect.
  • British, Australian, and Canadian English spell it "cancelled" with two L's.
  • Both spellings are correct in their respective regions, so choose based on your audience or the spell-check language you have selected.
  • The difference comes from a rule about doubling consonants before adding suffixes, which American and British English handle differently.
  • If your spell-checker is flagging one version as wrong, you may need to change your language settings to match your intended audience.

Why American and British English differ on this word

The rule about doubling consonants exists in both American and British English, but they apply it differently. In British English, when a word ends in a single consonant preceded by a single vowel, you double that consonant before adding a suffix. "Cancel" ends in L, preceded by the vowel E, so British writers write "cancelled." American English simplified this rule over time and tends not to double the consonant in words where the stress does not fall on the final syllable. Since "cancel" is stressed on the first syllable (CAN-cel), American English keeps the single L.

This same pattern shows up in other words too. "Travelled" (British) versus "traveled" (American), "labelled" (British) versus "labeled" (American), and "modelled" (British) versus "modeled" (American) all follow the same rule. Understanding this pattern helps you remember which spelling goes with which region.

How to set your spell-checker to the right English variant

If your spell-checker keeps flagging the spelling you want to use, you can change the language setting. In Microsoft Word, go to the Review tab, select "Language," and choose either "English (United States)" for American spelling or "English (United Kingdom)," "English (Australia)," or "English (Canada)" for the two-L version. Once you change this setting, the spell-checker will accept "cancelled" or "canceled" depending on which you selected.

In Google Docs, click the Tools menu, select "Language," and pick your region. On a Mac using Apple's built-in spell-check, go to System Preferences, then Keyboard, then Text, and adjust the spelling dictionary. Most email clients and online writing tools have similar language settings buried in their preferences or settings menu. If you write regularly for a specific region, setting this once saves you from having to override the spell-checker every time.

When you are unsure which spelling to use

If you do not know which English variant your audience uses, American English is the safer default for most online writing. American English is the standard for most US-based websites, social media platforms, and software. However, if you are writing for a company, publication, or person based in the UK, Australia, or Canada, use the two-L spelling. If you are writing for an international audience with no clear regional focus, check whether the organization or publication has a style guide that specifies which English variant they use.

When in doubt, pick one and stay consistent throughout your document. Switching between "canceled" and "cancelled" in the same piece of writing looks like a mistake, even though both spellings are technically correct in different regions.

Other words that follow the same doubling rule

Once you understand the consonant-doubling rule, you can predict which other words will differ between American and British English. Words like "committed," "omitted," "permitted," "admitted," and "submitted" all have British versions with double T's ("committed," "omitted," etc.) that are also spelled with double T's in American English — because the stress falls on the final syllable in these words, so both regions double the consonant. But "benefit" becomes "benefited" in American English and "benefitted" in British English, because the stress falls on the first syllable.

The pattern is consistent once you know it: British English doubles the final consonant more often, American English does it less often. This rule applies to words ending in L, T, S, and other consonants. Knowing this helps you understand not just "cancelled" but dozens of other spelling differences between the two variants.

Frequently Asked Questions

Is "cancelled" with two L's wrong in America?

No, it is not wrong — it is just not the American standard. If you write "cancelled" in the US, most American spell-checkers will flag it as a spelling error, but the word itself is not incorrect. It is simply the British, Australian, or Canadian spelling. In a formal document for an American audience, use "canceled" with one L to match the expected standard.

Which spelling do most websites use?

Most major US websites and tech companies use "canceled" with one L because they follow American English standards. However, websites based in the UK, Australia, or Canada use "cancelled" with two L's. If you are building a website or writing for a specific company, check their style guide or existing content to see which they use.

Will spell-check automatically fix this for me?

Only if your spell-checker is set to the right language variant. If your spell-checker is set to American English and you type "cancelled," it will flag it as an error. You can either change your language setting or right-click and add the word to your dictionary if you want to use the British spelling regularly.

What if I am writing for an international company?

Check the company's style guide first — most large organizations specify which English variant they use in their internal documentation. If there is no style guide, ask your manager or editor. If you still cannot find out, American English is the most common default for international companies, so "canceled" with one L is usually the safest choice.
