If you’ve ever stopped while writing and wondered whether the correct word is appal or appall, you’re not alone. The two spellings look different enough to suggest that they might have different meanings. In reality, they refer to the same verb and describe the same basic idea: causing someone to feel strong shock, horror, or disapproval.
The real difference comes down to English spelling conventions. Appal is the standard British English spelling, while appall is the standard American English spelling. The distinction becomes especially useful when you’re writing for a specific audience because spelling consistency matters in professional, academic, and published content.
There are a few details that make this word pair more interesting than it first appears. The spelling changes in the base form, yet forms such as appalled and appalling use two ls in both varieties. The word also has a long history that reaches back to Middle English.
Quick Answer
Appal and appall have the same meaning. Both are verbs that mean to cause someone to feel intense shock, horror, disgust, or disapproval.
The main difference is regional spelling:
- Appal = British English
- Appall = American English
- Appalled = used in both varieties
- Appalling = used in both varieties
For example:
British English: The report may appal the public.
American English: The report may appall the public.
Neither spelling changes the meaning of the sentence.
If you’re writing in US English, use appall. If you’re following standard British English, use appal.

Main Differences Between Appal vs Appall
There is only one major difference between appal vs appall: spelling by English variety.
The meaning doesn’t change. The pronunciation doesn’t become a different word. The emotional intensity doesn’t increase because one version has another l.
Appal Is the British Spelling
Appal is the conventional spelling used in British English.
For example:
The discovery of the unsafe conditions appalled the inspectors.
Notice something important here. Even though the British base form is appal, the past tense is appalled with two ls.
Another example:
The behavior of the officials appalled the committee.
The same spelling applies whether you’re writing for readers in England, Scotland, Wales, or another audience that follows British spelling conventions.
Appall Is the American Spelling
Appall is the standard American English spelling.
For example:
The evidence appalled the investigators.
Or:
The treatment of the animals appalled the public.
American dictionaries commonly use the double-l spelling in the base form. That’s why American writers will generally choose appall, not appal.
The Meaning Does Not Change
This is the point that causes the most confusion.
You shouldn’t interpret the extra l as a change in meaning.
These sentences communicate essentially the same thing:
The decision appalled the community.
The decision appalled the community.
The distinction would only become visible if the sentences used the base form:
The decision may appal the community. — British spelling
The decision may appall the community. — American spelling
The underlying verb remains the same.
What Does Appal Mean?
Appal means to cause someone to experience strong shock, horror, distress, or disapproval.
It’s generally stronger than simply saying that something surprised someone.
For example:
The scale of the environmental damage appalled the researchers.
This sentence suggests more than surprise. The researchers found the situation deeply disturbing.
The word often appears when someone reacts strongly to:
- Cruel behavior
- Serious wrongdoing
- Disturbing conditions
- Extreme negligence
- Offensive conduct
- Moral failures
- Shocking events
- Severe social problems
Consider the difference:
The price surprised me.
versus:
The conditions at the facility appalled me.
The first sentence describes an unexpected discovery. The second suggests a much stronger emotional response.
Examples of Appal in British English
Here are several natural examples:
- The report may appal readers who weren’t aware of the conditions.
- The evidence appalled the investigators.
- The level of neglect appalled the inspectors.
- The decision appalled many members of the public.
- She was appalled by the treatment of the workers.
These examples demonstrate why appal often carries a serious emotional or moral dimension.
What Does Appall Mean?
Appall has the same meaning as appal. It means to cause someone to feel intense shock, horror, or disapproval.
American writers typically use this spelling.
For example:
The findings appalled the medical team.
The sentence tells us that the findings caused a powerful negative reaction.
Another example:
The investigators were appalled by the condition of the building.
Here, appalled describes the investigators’ emotional response.
Examples of Appall in American English
- The evidence appalled the jury.
- The decision appalled thousands of residents.
- The report appalled environmental groups.
- The level of corruption appalled the investigators.
- She was appalled by what she saw.
The strength of the word depends partly on context. A writer can use appall for emotional shock, moral disapproval, horror, or a combination of these reactions.
Is Appal or Appall Correct?
Both are correct.
The better choice depends on the variety of English you’re using.
If your audience expects American English, choose appall.
If your audience expects British English, choose appal.
This is similar to other regional spelling differences such as:
- color vs. colour
- center vs. centre
- favorite vs. favourite
- organize vs. organise in many style systems
The important lesson is that a regional spelling isn’t automatically an error.
Which Spelling Should American Writers Use?
American writers should generally use:
appall
For example:
The findings appall researchers.
The conditions appalled the inspectors.
The report describes an appalling situation.
If you’re writing a US-focused website, academic paper, business document, or article, appall is the straightforward choice.
Which Spelling Should British Writers Use?
British writers generally use:
appal
For example:
The findings appal researchers.
The conditions appalled the inspectors.
The report describes an appalling situation.
Notice again that the past tense and participle contain two ls.
Appal vs Appall in Different Verb Forms
The spelling difference becomes especially interesting when you conjugate the verb.
| Verb form | British English | American English |
| Base form | appal | appall |
| Third-person singular | appals | appalls |
| Past tense | appalled | appalled |
| Past participle | appalled | appalled |
| Present participle | appalling | appalling |
This means that the distinction between the two varieties is most obvious in the base form and third-person singular form.
Present Tense
British:
The decision may appal the public.
American:
The decision may appall the public.
Third person:
The decision appals the public. — British
The decision appalls the public. — American
Past Tense
Both varieties use:
appalled
Examples:
The report appalled the committee.
The discovery appalled the investigators.
You don’t normally write appaled.
Present Participle
Both varieties use:
appalling
Examples:
The conditions were appalling.
The report revealed appalling neglect.
You don’t write appaling.
That distinction is worth remembering because writers sometimes assume that the British base form appal should produce appaled. It doesn’t.
Appalled vs Appalling
Although appalled and appalling come from the same verb, they perform different grammatical jobs.
What Does Appalled Mean?
Appalled usually describes the person or group experiencing the reaction.
For example:
The residents were appalled by the proposal.
The residents feel shock or strong disapproval.
Another example:
I was appalled by the condition of the building.
The speaker experienced the emotional reaction.
A useful shortcut is:
People are appalled.
What Does Appalling Mean?
Appalling generally describes the thing that causes the reaction.
For example:
The conditions were appalling.
The conditions caused shock or horror.
Another example:
The investigation uncovered appalling negligence.
The negligence itself creates the reaction.
A useful shortcut is:
Things are appalling.
Compare these two sentences:
The workers were appalled by the conditions.
The conditions were appalling.
That distinction makes the grammar much easier to understand.

How Do You Pronounce Appal and Appall?
The spelling difference doesn’t normally create a meaningful pronunciation difference.
Both forms are pronounced essentially the same way in standard English.
That creates an interesting practical problem: you can’t usually hear whether someone intends to write appal or appall.
The distinction matters primarily on the page.
This is why the choice becomes an editing issue rather than a pronunciation issue. If you’re preparing written material for an American audience, use appall. If you’re following British conventions, use appal.
Common Examples of Appal vs Appall
The following examples show how the two spellings work in real sentences.
| British English | American English |
| The evidence may appal the public. | The evidence may appall the public. |
| The decision appals many readers. | The decision appalls many readers. |
| The report appalled investigators. | The report appalled investigators. |
| The conditions were appalling. | The conditions were appalling. |
The first two rows show the spelling difference clearly. The last two demonstrate how the difference largely disappears in common inflected forms.
Example in Journalism
The findings appalled officials who had expected a minor problem.
This works well when reporting on a serious discovery or disturbing situation.
Example in Business Writing
The audit findings appalled the company’s leadership.
Here, the verb communicates a reaction stronger than ordinary concern.
Example in Academic Writing
Researchers were appalled by the extent of the contamination.
Academic writing can use the word naturally when describing a strong reaction to evidence.
Example in Everyday Conversation
I was appalled by how rudely they treated the customer.
The word isn’t restricted to formal writing. People use it in ordinary conversation when they want to emphasize strong disapproval.
Common Mistakes With Appal and Appall
Understanding the spelling rule prevents several common errors.
Mistake: Treating Appal as Incorrect
A writer might see appal and assume someone forgot an l.
That’s incorrect when the text follows British English conventions.
Appal is a legitimate British spelling.
Mistake: Assuming Appal and Appall Have Different Meanings
They don’t.
The difference isn’t comparable to pairs such as affect and effect, where the words perform different grammatical roles and have different meanings.
With appal vs appall, you’re dealing with a regional spelling distinction.
Mistake: Writing Appaled
The correct form is:
appalled
It has two ls.
Incorrect:
The discovery appaled the researchers.
Correct:
The discovery appalled the researchers.
Mistake: Writing Appaling
The correct form is:
appalling
Again, it has two ls.
Incorrect:
The conditions were appaling.
Correct:
The conditions were appalling.
Mistake: Mixing Spelling Systems
Regional spelling isn’t a problem. Inconsistency is.
If an American article uses color, center, and favorite, using appal in the same article may look inconsistent.
Likewise, a British publication that consistently follows British spelling will normally prefer appal.
Choose a spelling system and stick with it.
Why Are Appal and Appall Spelled Differently?
The history of this word goes back centuries.
Merriam-Webster traces appall to Middle English forms including apallen and appallen. The word’s history is connected with the idea of becoming pale or causing someone to become pale through fear or shock. Merriam-Webster records its first known use in the 14th century.
That history fits the modern meaning surprisingly well.
Imagine encountering something so frightening or disturbing that you visibly lose color. The older sense connects physical paleness with intense emotional shock.
Over time, English spelling developed regional conventions. American and British English eventually settled on different spellings for the base form:
British: appal
American: appall
The difference doesn’t mean that American and British speakers developed two separate words. They retained the same underlying verb while standard spelling conventions diverged.
Appal vs Appall and Related Words
Appall has several related words, but they aren’t perfect substitutes in every sentence.
| Word | General meaning | Typical emphasis |
| Appall | Cause intense shock or disapproval | Strong emotional reaction |
| Horrify | Cause extreme fear, shock, or disgust | Horror or terror |
| Shock | Cause strong surprise or distress | Unexpected event |
| Dismay | Cause distress or loss of confidence | Worry or discouragement |
| Disgust | Cause intense revulsion | Strong dislike or revulsion |
Consider this example:
The news shocked the community.
This doesn’t necessarily tell us that people found the news morally offensive.
Now compare:
The news appalled the community.
This suggests a deeper reaction involving horror, outrage, or strong disapproval.
Finally:
The news disgusted the community.
This emphasizes revulsion.
These words overlap, but each carries its own shade of meaning.
