If you’ve ever paused mid-sentence wondering whether to type “appal” or “appall,” you’re not alone. This is one of the most common spelling mix-ups in the English language, and honestly, it trips up native speakers just as often as learners. As an English teacher, I get this question a lot, so let’s settle it once and for all.
The short answer: appal is the British English spelling, and appall is the American English spelling. Both mean the same thing — to shock or horrify someone deeply. But there’s more nuance here than a simple spelling rule, and understanding it will make you sound more polished in both spoken and written English.
Let’s break it down completely, the way a teacher would explain it in class — with meaning, grammar, pronunciation, history, and plenty of real examples.
Why Do People Mix Up Appal and Appall So Often?
The confusion happens for three main reasons.
First, the words look almost identical. One letter — a single “l” — is the only visible difference. Our brains often skim over small spelling variations, especially when a word isn’t used every day.
Second, most people are exposed to both British and American English through movies, books, websites, and social media. Without realizing it, you absorb spelling habits from multiple sources, which makes it easy to blend them.
Third, spell-checkers don’t always help. If your device is set to US English, it will flag “appal” as wrong. If it’s set to UK English, it will flag “appall.” Neither is actually wrong — it depends entirely on which English variety you’re writing in.
Quick Tip: If your spell-checker underlines one version, check your language settings before assuming you made a mistake.
Do Appal and Appall Mean the Same Thing?
Yes. This is the most important thing to understand before anything else. Appal and appall are not two different words with different meanings — they are the exact same word, spelled two different ways depending on the English dialect you’re using.
Definition in Plain English
Both appal (British) and appall (American) mean:
To fill someone with horror, shock, or disgust; to dismay someone strongly.
If something appalls you, it makes you feel a mix of shock and moral disapproval. It’s a strong emotional reaction — not mild annoyance, but genuine horror or revulsion.
Example: The conditions in the abandoned building appalled the inspectors.
This sentence means the inspectors were deeply shocked and horrified by what they saw.
The Emotion These Words Express
Think of appal/appall as sitting at the intense end of the “shock” spectrum. It’s stronger than “surprise,” stronger than “upset,” and closer to words like “horrify” or “disgust.”
Here’s a rough emotional scale, from mild to intense:
- Surprised → mild reaction
- Disappointed → mild-to-moderate reaction
- Shocked → moderate-to-strong reaction
- Appalled → strong, often moral or emotional horror
- Horrified → extremely strong, often physical or visceral reaction
When you say you’re “appalled,” you’re communicating that something crossed a line — ethically, morally, or emotionally.
Appal vs. Appall: The Main Difference Explained
Now let’s get into the actual difference, because this is what most people are searching for.
British English Spelling (Appal)
In British English, and in most Commonwealth countries — including Australia, New Zealand, South Africa, and India — the correct spelling is appal, with one “L.”
Example (British English): Her comments appal me every time I hear them.
American English Spelling (Appall)
In American English, the correct spelling is appall, with two “L”s at the end.
Example (American English): Her comments appall me every time I hear them.
Notice the sentence is identical — only the spelling changes based on the English variety.
Which Spelling Should You Use?
Use this simple rule:
| If you’re writing for… | Use this spelling |
| A US audience, US publication, or US-based company | Appall |
| A UK, Australian, Canadian (mostly), or Commonwealth audience | Appal |
| An international or mixed audience | Pick one and stay consistent |
Quick Tip: Canadian English is a hybrid. Many Canadian style guides accept both, but “appall” (American style) is more common in everyday Canadian writing.
Appal vs. Appall Comparison Table
Here’s a full side-by-side comparison to keep for quick reference.
| Feature | Appal (British) | Appall (American) |
| Spelling | One “L” at the end | Two “L”s at the end |
| Region | UK, Australia, NZ, South Africa, India | United States |
| Meaning | To shock or horrify | To shock or horrify |
| Pronunciation | uh-PAWL | uh-PAWL |
| Past tense | Appalled | Appalled |
| Present participle | Appalling | Appalling |
| Adverb form | Appallingly | Appallingly |
| Third-person singular | Appals | Appalls |
Interesting fact: even though the base spelling differs, the past tense (“appalled”) and the present participle (“appalling”) are spelled the same way in both British and American English. The difference only shows up in the base verb and the third-person singular form.
Pronunciation: Do Appal and Appall Sound Different?
No — this is good news. Despite the spelling difference, appal and appall are pronounced exactly the same way.
Both are pronounced: uh-PAWL (rhymes with “small” or “call”).
- Stress falls on the second syllable.
- The “a” at the start sounds like the “a” in “about.”
- The ending sounds like “all,” as in “hall” or “wall.”
So if you’re speaking rather than writing, you don’t need to worry about this distinction at all. The spelling difference only matters in written English.
Quick Tip: Since pronunciation is identical, this is purely a writing and formatting issue — not a speaking one. Save your attention for when you’re typing, emailing, or publishing.
Word Origin and Etymology
Understanding where this word comes from makes it much easier to remember and use correctly.
From Latin to Old French
The word traces back to the Latin word pallere, meaning “to be pale” or “to grow pale.” This root also gives us the word “pale” and “pallid.”
From Latin, the word passed into Old French as apalir, meaning “to grow pale” or “to make pale.” The idea was that fear or shock could literally drain the color from someone’s face.
By the time it entered Middle English, the word had shifted meaning slightly — from describing physical paleness to describing the emotional shock that causes it.
How British and American Spellings Evolved
The spelling split between “appal” and “appall” is part of a much bigger pattern in English. American spelling reform, largely driven by lexicographer Noah Webster in the early 1800s, simplified many British spellings.
Webster’s dictionary aimed to make American English more phonetic and, in some cases, more consistent. This is the same reason Americans write “color” instead of “colour,” and “traveled” instead of “travelled.”
However, “appall” is a bit of an exception to Webster’s usual pattern of removing extra letters. In this case, American English actually added a letter, doubling the final “L” instead of simplifying it. Language historians believe this happened because “appall” follows the same doubling pattern as similar English verbs like “install” and “recall,” which also end in double “L” in American usage.
Grammar Forms of Appall (And Appal)
Let’s cover the grammar carefully, since this trips people up in both spelling systems.
Appals / Appalls (Third-Person Singular, Present Tense)
- British: appals — The news appals him.
- American: appalls — The news appalls him.
Appalled (Past Tense and Past Participle)
This spelling is the same in both British and American English.
- She was appalled by the mess in the kitchen.
- He appalled his colleagues with his rude comments.
Appalling (Present Participle / Adjective)
Also spelled the same in both varieties.
- The appalling smell forced everyone to leave the room.
- Traffic conditions were appalling this morning.
Notice that “appalling” is also commonly used as an adjective, not just a verb form.
Appallingly (Adverb)
Same spelling in both British and American English.
- The team performed appallingly during the final match.
- He behaved appallingly at the dinner party.
Grammar Tip: Since three out of four grammar forms are spelled identically in both dialects, the only form you truly need to double-check is the base verb and its third-person singular version.
How to Use Appal Correctly (British English)

Notice how, aside from the spelling of the base word, everything else about usage stays consistent.
Appal vs. Appall in British, American, and International English
Here’s a broader look at how different English-speaking regions handle this word.
| Region | Preferred Spelling |
| United States | Appall |
| United Kingdom | Appal |
| Australia | Appal |
| New Zealand | Appal |
| South Africa | Appal |
| India | Appal |
| Canada | Mixed (often Appall, following US influence) |
If you’re writing for an international or global audience — say, for a multinational company’s website — many style guides recommend defaulting to American spelling (appall) simply because it’s the most widely recognized in global business and digital content. However, if your audience is clearly UK-based or Commonwealth-based, stick with appal.

Common Mistakes People Make
Appal/Appall vs. Appeal
This is a big one. “Appal/appall” and “appeal” look somewhat similar but mean opposite things.
- Appall = to shock or horrify (negative)
- Appeal = to attract, request, or be attractive to (usually positive or neutral)
Incorrect: The movie appalled to a wide audience. Correct: The movie appealed to a wide audience.
Correct: The violence in the movie appalled many viewers.
Mixing UK and US Spellings
A common mistake is switching spelling styles within the same document.
Incorrect: I was appalled, and to be honest, it still appals me. (mixing “appalled” — fine, it’s the same in both — with “appals,” which is British, while the rest of the document uses American spelling)
Correct (US): I was appalled, and to be honest, it still appalls me.
Correct (UK): I was appalled, and to be honest, it still appals me.
Quick Tip: Pick one spelling system at the start of your document and stay consistent through every form of the word.
Incorrect Verb Forms
Some learners mistakenly double the “L” in British spelling or use only one “L” in American spelling for the base verb.
Incorrect (in US English): That behavior really appals me. Correct (in US English): That behavior really appalls me.
Incorrect (in UK English): That behavior really appalls me. Correct (in UK English): That behavior really appals me.
Memory Tricks to Remember Appal vs. Appall
Here are a few simple tricks I share with my students:
- “America adds letters.” Just like “color” becomes “colour” going the other way, remember that American English often adds or changes letters compared to British spelling. Appall has that extra “L” — think “American = Additional L.”
- Count the countries, count the L’s. Britain has one official “L” in its short-form name pattern in your head (just a memory anchor) — appal, one L. America — appall, double L, like “all” doubled.
- Link it to “install” and “recall.” American English doubles the final “L” in verbs like “install,” “recall,” and “appall.” If you already spell those correctly, use the same pattern for “appall.”
- British keeps it short. British spelling in this case is the shorter, simpler version — appal, single L, matches the general British tendency toward more streamlined verb endings.

Frequently Asked Questions
Is “appal” a real word, or is it a misspelling of “appall”? Appal is a completely real, correctly spelled word — it’s simply the British English spelling. It’s not a typo or an error. If you’re writing in UK, Australian, or most Commonwealth English, “appal” is the correct choice, just as “appall” is correct in American English.
Which spelling should I use on my website or blog? It depends on your target audience. If most of your readers are in the US, use “appall.” If you’re writing for a UK or international Commonwealth audience, use “appal.” For global content, many writers default to American spelling since it has wider digital reach.
Is “appalled” spelled differently in British and American English? No. “Appalled” is spelled the same way in both dialects. The spelling difference only appears in the base verb form (“appal” vs. “appall”) and the third-person singular form (“appals” vs. “appalls”).
Do appal and appall sound different when spoken? No, they sound identical. Both are pronounced “uh-PAWL,” with stress on the second syllable. The difference between these two words exists only in writing, not in speech.
What’s the difference between appalled and appealed? These words are unrelated in meaning, despite looking somewhat similar. “Appalled” means shocked or horrified, while “appealed” means attracted, requested, or made a formal request. Mixing them up is a common but easily avoidable mistake.
Can I use “appal” and “appall” interchangeably in the same document? It’s not recommended. Mixing British and American spellings within one document looks inconsistent and unprofessional. Choose one spelling system based on your audience and stick with it throughout your writing.
Where does the word “appal/appall” come from? It comes from the Latin word “pallere,” meaning “to grow pale,” through Old French “apalir.” Originally, the word described becoming pale from fear or shock, and it later evolved to describe the emotional shock itself.
Is “appalling” always negative? Almost always, yes. “Appalling” describes something shocking, disgraceful, or disturbing in a negative sense. It’s rarely, if ever, used to describe something positive or neutral.
Which spelling is used in Canada? Canadian English is a blend of British and American conventions. While some Canadian style guides accept “appal,” the American spelling “appall” is more commonly seen in everyday Canadian writing and media.
Is one spelling considered more “correct” than the other? No. Neither spelling is more correct in an absolute sense. Correctness depends entirely on which English variety you’re using. “Appal” is correct for British English, and “appall” is correct for American English.

These short drills are useful because they force you to apply both the spelling rule and the meaning distinction at the same time, which is exactly how the word shows up in real writing.
Why This Spelling Distinction Matters for Writers and Businesses
If you write professionally — whether for a blog, a company website, an academic paper, or client communications — spelling consistency is part of how readers judge credibility. A single inconsistent word won’t ruin your writing, but a pattern of mixed spellings can make content feel unpolished or poorly edited.
This matters even more for businesses operating internationally. A company based in London writing marketing copy for American clients should switch to “appall” (and other American conventions like “color,” “organize,” and “traveled”) to feel native to that audience. The reverse is true for American companies expanding into UK or Australian markets.
Content editors, copywriters, and translators often keep a personal style sheet — a running list of word choices like this one — to stay consistent across long projects. If you write regularly, it’s worth creating your own quick-reference list for commonly confused British and American spellings, including pairs like:
| British | American |
| Appal | Appall |
| Colour | Color |
| Organise | Organize |
| Travelled | Traveled |
| Centre | Center |
| Analyse | Analyze |
| Programme | Program |
| Defence | Defense |
Notice that “appal/appall” doesn’t follow the exact same pattern as most of these — in most cases, British English uses more letters (colour, organise, travelled), while American English simplifies. With “appal/appall,” it’s the opposite: American English adds the extra letter. This is exactly why it trips up so many writers, even those who are otherwise confident with British versus American spelling conventions.
A Teacher’s Perspective: How I Explain This to Students
When I teach this distinction in class, I tell students to think of “appal/appall” as a single word with a passport. Depending on which country it’s “traveling” in, it wears a slightly different spelling — but its identity, meaning, and personality never change.
I also remind students that this is not a word you’ll use every day, but it shows up often in journalism, formal writing, reviews, and opinion pieces, because it expresses strong moral or emotional judgment. Learning it properly is less about memorizing a rule and more about training your eye to notice regional spelling patterns in general — a skill that pays off far beyond just this one word pair.
If you take one thing away from this lesson, let it be this: don’t just memorize “appal” or “appall” in isolation. Learn to recognize the broader British-versus-American spelling pattern, and this word — along with dozens of others — will start to make intuitive sense.
Final Thoughts
Appal and appall are the same word wearing two different regional outfits. Once you understand that the difference comes down to British versus American spelling conventions — not meaning, not pronunciation, and not grammar rules beyond the base verb — this word stops being confusing.
The safest approach is simple: identify your audience first, then choose your spelling and stay consistent. Remember that “appalled,” “appalling,” and “appallingly” are spelled the same way everywhere, so you only need to think carefully about the base verb form. With that one small rule in mind, you’ll never second-guess this word again.
