Travelling or Traveling? Which Is Correct in British English?

The Rule Behind the Double L

The difference between travelling and traveling is not arbitrary — it follows a clear grammatical rule that applies to verbs ending in a single L preceded by a single vowel.

In British English, when you add a suffix beginning with a vowel (such as -ing, -ed or -er) to a verb that ends in a single L preceded by a single vowel, you double the L. This is a standard British English spelling rule:

• travel + -ing = travelling
• travel + -ed = travelled
• travel + -er = traveller

In American English, the L is not doubled in these cases. The suffix is simply added without doubling:

• travel + -ing = traveling
• travel + -ed = traveled
• travel + -er = traveler

Travelling in British English

In British English, travelling — with double L — is the correct and expected spelling in all contexts. This applies to all forms of the word derived from the verb to travel:

• Travelling — present participle: She is travelling to Edinburgh next week.
• Travelled — past tense: He had travelled extensively before settling in London.
• Traveller — noun: The traveller arrived at the station just before midnight.
• Well-travelled — adjective: She is a well-travelled writer with experience across four continents.

British English also uses the double L in related compound words and phrases: fellow traveller, time traveller, long-distance traveller.

Traveling in American English

In American English, traveling — with a single L — is standard. American spell-checkers will flag travelling as incorrect, and American publications use traveling consistently. The same applies to traveled and traveler.

The single-L convention in American English was part of the broader spelling simplifications associated with Noah Webster in the eighteenth and nineteenth centuries, which regularised a number of double-consonant spellings that had existed in British English.

Other Words That Follow the Same Rule

Travelling and traveling are part of a significant group of words where British English doubles the L and American English does not. Here are the most common examples you are likely to encounter in academic and professional writing:

If you are writing in British English, the double L rule applies consistently across all of these words. Setting your spell-checker to British English is the quickest way to catch any single-L Americanisms that might creep into your writing.

Examples in Context

British English — Travelling (Double L)

• She spent three months travelling through Southeast Asia before starting her PhD.
• The research involved travelling to four different archive sites across the UK.
• As an experienced traveller, she was well prepared for the conference in Berlin.

Common Mistakes in British English Documents

• Incorrect: The researcher spent six months traveling between field sites. Correct: The researcher spent six months travelling between field sites.
• Incorrect: The meeting was canceled at short notice. Correct: The meeting was cancelled at short notice.
• Incorrect: Data was collected using a modeled approach. Correct: Data was collected using a modelled approach.

Why It Matters in Professional and Academic Writing

In academic writing submitted to UK universities, British English spelling is the expected standard. Using American spellings — including traveling instead of travelling — is a consistency error that tutors and examiners notice. In some institutions, persistent use of American English conventions can affect your mark for written expression.

In professional writing for UK audiences, the same principle applies. A business report, client proposal or published article that uses American spellings signals to a British readership that the document has not been carefully proofread.

The double-L words are particularly easy to miss because American spell-checkers will not flag them as errors — they are simply the correct American English spelling. This makes them one of the most common consistency issues in British English documents that have been drafted or edited using American English software settings.

Frequently Asked Questions

Is it travelling or traveling in the UK?

In the UK, travelling — with double L — is the correct British English spelling. Traveling (with a single L) is the American English spelling. Using traveling in a British English document is considered an Americanism and would be flagged as an error in formal or academic writing.

Why does British English double the L in travelling?

British English doubles the L in travelling because of a standard spelling rule: when you add a vowel suffix (-ing, -ed, -er) to a verb ending in a single L preceded by a single vowel, you double the L. This rule applies across a large group of verbs including cancel, label, model and signal.

Is travelled or traveled correct in British English?

In British English, travelled — with double L — is correct. Traveled (with a single L) is the American English form. The same double-L rule that gives us travelling also gives us travelled and traveller.

Does Australian English use travelling or traveling?

Australian English follows British conventions and uses travelling — with double L. The same applies to New Zealand and Irish English. Canadian English generally follows American conventions and uses traveling with a single L.

What other words follow the same double-L rule in British English?

Many common verbs follow the same rule in British English, including: cancel (cancelling, cancelled), label (labelling, labelled), model (modelling, modelled), signal (signalling, signalled), equal (equalling, equalled), marvel (marvelling, marvelled) and fuel (fuelling, fuelled). All of these take double L before a vowel suffix in British English but single L in American English.

Will my spell-checker catch this mistake?

Only if it is set to British English. If your spell-checker is set to American English — which is the default for many software applications including Microsoft Word when first installed — it will not flag traveling as an error because it is the correct American spelling. Always check that your spell-checker language setting matches the variety of English you are writing in.
