If you’ve ever typed this word and paused — wondering whether it needs one L or two — you’re in good company. Even professional editors double-check it. The short answer: appal vs appall are the same word. One is British English, the other is American English. But there’s a lot more to know if you want to use either form with real confidence.
Why Do Writers Mix Up Appal and Appall?
The confusion is completely understandable, and it comes down to one hidden cause: where you learned English shapes what looks “right” to you.
If you grew up reading British newspapers, textbooks, or novels, your brain stored appal as the correct form through thousands of repeated exposures. If you learned from American sources, appall feels natural. The trouble starts when writers cross regional lines — submitting work to a foreign publisher, writing for an international blog, or editing someone else’s copy.
There’s also a technological layer to this confusion. Most spell-checkers default to one regional setting. Set your software to US English and it flags appal with a red underline. Switch to UK English and appall gets the squiggly treatment instead. Neither spelling is wrong — the software just doesn’t know your audience.
The result? A word that genuinely has two correct forms regularly gets “corrected” into an error.
Where Did Appal and Appall Come From?
The Latin and French Roots
Both spellings share a single origin, and it’s a vivid one. The journey begins with the Latin verb pallēre, meaning to be pale or to grow pale. Romans used it to describe the color draining from a person’s face in moments of terror or shock — a physical, visible reaction to horror.
Old French inherited this root as apalir — combining the prefix a- (meaning “to”) with palir (to grow pale). The image stayed the same: something so disturbing it blanches your face. Medieval English borrowed the Old French form and it entered Middle English as appallen around the 14th century, first recorded in the sense of “to fade” and later, by the 1530s, acquiring its modern meaning of to cause dismay or shock.
The transitive meaning — using the word to describe what one thing does to another — has been standard since the 1500s. The word’s emotional punch has only deepened over time.
Webster’s American Spelling Reforms
The British-American spelling split didn’t happen by accident. It was the result of deliberate language policy, driven largely by one man: Noah Webster.
In 1828, Webster published his landmark American Dictionary of the English Language, which standardized dozens of American spellings that diverged from British usage. His reforms aimed to give American English its own identity, and appall (with the double L) was cemented as the American standard.
British lexicographers took their own path. The Oxford English Dictionary settled on appal as the preferred British form. From that point, the two spellings lived separate but equal lives on opposite sides of the Atlantic — not rivals, but siblings with different addresses.
How Do You Use Appal vs Appall in Different Contexts?
The meaning never changes. What changes is the spelling you choose based on your target audience.
Quick Reference Table
| Spelling | Region | Style Guides | Example |
|---|---|---|---|
| Appall | American English | AP Style, Chicago | The report appalled the committee. |
| Appal | British English | Oxford, Guardian Style | The report appalled the committee. |
| Appalled | Universal | Both | She was appalled by the decision. |
| Appalling | Universal | Both | The conditions were appalling. |
Key insight: While the base verb splits by region, the inflected forms appalled and appalling always take the double L — in every dialect, every style guide, every context.
British English Writing
In the UK, Australia, New Zealand, and most Commonwealth countries, appal is the expected spelling in formal writing.
- The charity was appalled by the government’s lack of response.
- It appals me to think anyone could condone such behaviour.
- His conduct at the meeting appalled every senior member of the board.
British newspapers like The Guardian and The Times, as well as the BBC, consistently use the single-L form in editorial content.
American English Writing
In the United States and Canada, appall is standard across journalism, academic writing, and publishing.
- The documentary appalled viewers across the country.
- It appalls me that this practice continues unchecked.
- The jury was visibly appalled by the evidence presented.
The Associated Press Stylebook and the Chicago Manual of Style both treat appall as the default American form.
International and Global Contexts
For writing aimed at a global audience — international websites, academic journals with mixed readership, or multinational corporate communications — the guidance is simple:
- Pick one spelling and use it throughout the entire document.
- Match your primary audience. If most readers are American, use appall.
- Check your publisher’s house style before submitting any formal work.
- Set your spell-checker’s regional language before you begin writing.

Where Have Writers Used These Words Throughout History?
Classic British Literature
British writers from the Victorian era and beyond used appal in its single-L form. The word appeared regularly in 19th-century novels to describe moral outrage, social injustice, and emotional devastation — all themes that demanded a word with genuine weight behind it.
American Literature and Journalism
American writers, following Webster’s standardization, adopted appall firmly by the mid-19th century. The word became a staple of American journalism, particularly in coverage of social reform movements, wars, and political corruption — contexts where expressing genuine moral horror was essential.
Contemporary Global Writing
Google Ngram data tells an interesting story. Before 1900, appal dominated in both regions. By the mid-20th century, appall surged ahead in American publications while appal held steady in British usage. Today, because of the global reach of American media and digital content, appall is increasingly common even outside the US — though formal British writing still strongly favors appal.

Related Words with Regional Splits
Appal/appall isn’t alone. Several English words split the same way:
| British English | American English |
|---|---|
| Appal | Appall |
| Fulfil | Fulfill |
| Enrol | Enroll |
| Distil | Distill |
| Instil | Instill |
The pattern is consistent: British English tends to use a single final L where American English doubles it.
Visualizing Regional Spelling Patterns
To put it visually, think of the Atlantic Ocean as the dividing line:
West of the Atlantic (Americas):
appall → appalls → appalled → appalling
East of the Atlantic (UK + Commonwealth):
appal → appals → appalled → appalling
Notice that the past tense (appalled) and present participle (appalling) are identical on both sides. The split exists only in the base verb and the third-person present (appalls vs appals).
No Difference in Pronunciation
This is worth stating clearly because it sometimes surprises people: there is zero difference in how these words sound.
Both appal and appall are pronounced: / ə ˈ p ɔː l /
The stress falls on the second syllable. The word rhymes with fall, call, and hall. Whether you write one L or two, your mouth makes exactly the same sound.

Common Mistakes When Using Appal vs Appall
Knowing both spellings are valid doesn’t mean anything goes. Here are the real errors writers make:
- Mixing spellings within one document. Writing appal in one paragraph and appall in another signals carelessness, not flexibility.
- Using the wrong regional form for a formal submission. Submitting to a British academic journal with American spelling — or vice versa — suggests unfamiliarity with your audience.
- Doubling the L in inflected forms that already have it. Writing appallled (three L’s) is a straightforward typo, but it happens when writers overcorrect.
- Assuming appal is always a typo. American writers sometimes “fix” the perfectly correct British form, inadvertently introducing an error into someone else’s writing.
Tips for Using Appal vs Appall Correctly
Real-World Editing Experience
Professional editors follow a simple rule: never change a regional spelling without checking house style first. A British author’s appal is not an error — and treating it like one wastes time and creates friction.
For writers working across markets, many keep a style card near their desk noting which regional setting applies to each active project. It takes thirty seconds to set up and prevents dozens of inconsistencies.
Memory Tricks That Work
Need a quick mental anchor? Try these:
- “Appall” has ALL the letters — just like American English goes ALL in. Double the L, double the emphasis.
- “Appal” is brief, like British understatement. One L, clean and concise.
- Think of the word “fulfill.” Americans spell it with two Ls (fulfill); the British use one (fulfil). The same logic applies to appall/appal.
- Set your spell-checker before you start. This is the most practical tip of all — let your software flag inconsistencies automatically.
