Common Confusion About “Appall”
Many learners see the double l and assume that appall is a stronger version of appal.
It is not.
There is no normal difference in emotional strength between the two spellings. The difference comes from spelling conventions.
This is one of the most useful facts to remember about Appal vs Appall.
Difference Between Appal and Appall
The main difference in Appal vs Appall is the spelling convention used by different varieties of English.
Appal is mainly British English.
Appall is mainly American English.
Both mean to shock, horrify, or deeply upset someone.
Comparison Table
| Feature | Appal | Appall |
|---|---|---|
| Part of speech | Verb | Verb |
| Basic meaning | Shock or horrify | Shock or horrify |
| Common variety | British English | American English |
| Base spelling | One “l” | Two “l”s |
| Present form | appal | appall |
| Past tense | appalled | appalled |
| -ing form | appalling | appalling |
| Meaning difference | None in normal use | None in normal use |
| Formality | Neutral/formal | Neutral/formal |
The table makes the key point clear: the difference is mostly regional spelling.
British English vs American English
British English often uses one l at the end of the base form:
appal
American English generally uses two:
appall
This follows a broader spelling pattern seen in several English words.
Compare:
- fulfil / fulfill
- enrol / enroll
- instil / instill
- skilful / skillful
- appal / appall
The exact spelling rules can vary among words, so it is best to learn each common pair rather than assume one universal rule.
Is One Spelling More Correct?
No.
Both spellings are correct in the English variety where they are normally used.
If you are writing for a British audience, appal is usually the better choice.
If you are writing for an American audience, appall is usually preferred.
The most important thing is consistency.
If you choose British spelling, keep your other spelling choices British where appropriate. If your document follows American English, use American spelling consistently.
Grammar Logic
There is no major grammatical difference between the two.
Consider these sentences:
The story appalled me.
and:
The story appalled me.
They are identical in meaning and even identical in their past-tense spelling.
The distinction is visible mainly in the base form.
This is an important point in Appal vs Appall because learners sometimes look for a grammar rule that does not actually exist.
Sentence Structure
Both forms use the same grammar.
You can use the verb in a simple active sentence:
The news appalled Sarah.
You can also use the passive form:
Sarah was appalled by the news.
The adjective appalled is especially common in everyday English.
Another useful form is appalling:
The conditions were appalling.
Here, appalling means extremely bad, shocking, or horrible.
Meaning Comparison
There is no ordinary difference such as:
appal = slightly shocked
appall = extremely shocked
That would be incorrect.
Both forms can describe a very strong reaction.
The choice depends mainly on the spelling system you are following.
Grammar Rules You Must Remember
1. Both Forms Are Verbs
One of the first rules to remember about Appal vs Appall is that both are verbs.
They describe the action of causing someone to feel shocked or horrified.
For example:
The story appalled the audience.
The story is the thing causing the reaction.
2. Use an Object After the Verb
Because appal/appall is normally transitive, it commonly takes an object.
Pattern:
Subject + verb + object
Examples:
The news appalled him.
The decision appalled us.
The report appalled the public.
The object tells us who experienced the reaction.
A common learner error is to treat the verb like an adjective.
Do not write:
The news was appall me.
Instead, write:
The news appalled me.
Or:
I was appalled by the news.
3. “Appalled” Describes a Person’s Feeling
When you want to say that someone feels shocked or horrified, appalled is commonly used.
Examples:
I was appalled by his behavior.
She was appalled at the price.
They were appalled by the conditions.
Here, appalled works as a past participle and adjective.
This distinction is very useful for learners.
4. “Appalling” Describes the Thing Causing the Reaction
Use appalling when something itself is extremely bad or shocking.
For example:
The service was appalling.
The service caused a negative reaction.
Compare:
I was appalled by the service.
The service was appalling.
A simple way to remember it is:
People feel appalled. Things can be appalling.
5. The Past Tense Uses Double “L”
Even though British English spells the base form as appal, the past tense is:
appalled
The same is true of the American form:
appall → appalled
Examples:
The news appalled everyone.
The decision appalled the workers.
Her behavior appalled her friends.
Do not write apalled.
The correct spelling has two l’s:
appalled
6. The -ing Form Is “Appalling”
The present participle is:
appalling
not apaling.
Examples:
The smell was appalling.
The conditions were appalling.
It was an appalling mistake.
This form is widely used in both British and American English.
Common Mistakes Students Make
Why Do These Mistakes Happen?
The confusion usually comes from three things: pronunciation, regional spelling, and the double l in related forms.
When students hear the word, they cannot see whether it is written with one l or two.
Then they may notice that the past form is appalled in both varieties and wonder why the base forms look different.
Another problem is that learners sometimes think appal is a spelling mistake. It is not.
Mistake 1: Thinking “Appal” Is Wrong
Incorrect assumption:
Appal is always incorrect.
That is not true.
Appal is a standard spelling, especially in British English.
Likewise, appall is a standard spelling, especially in American English.
Mistake 2: Thinking the Meanings Are Different
Some learners believe one word means “surprise” while the other means “horrify.”
That is not the normal distinction.
The two forms have the same basic meaning.
The spelling is what changes.
Mistake 3: Writing “Apall”
A common spelling mistake is:
apall
The correct forms are:
appal
or:
appall
Both require two p’s.
Mistake 4: Writing “Apalled”
This spelling is also incorrect:
apalled
The correct spelling is:
appalled
There are two p’s and two l’s.
Mistake 5: Using “Appalling” for a Person’s Feeling
Incorrect:
I was appalling by the news.
Correct:
I was appalled by the news.
Why?
Appalled describes the person’s reaction.
Appalling describes something that causes that reaction.
Compare:
The story was appalling.
I was appalled by the story.
Mistake 6: Mixing Spelling Styles Without a Reason
Suppose you are writing a British English school assignment.
Using appal is appropriate.
If you are writing American English content, appall is generally preferred.
Neither choice is bad. The problem is careless inconsistency.
Easy Correction Tip
Before writing, ask:
“Which English style am I using?”
If it is British English:
appal
If it is American English:
appall
Then use that style consistently.
Easy Trick to Remember the Difference
The easiest memory trick for Appal vs Appall is:
British = APPAL
American = APPALL
Think of the extra L as an extra letter in the American spelling.
You do not need a complicated grammar formula.
A Simple Memory Sentence
Remember:
British English likes APPAL; American English likes APPALL.
This is not a rule that applies to every English word, but it works well for this particular spelling pair.
Another Helpful Trick
Look at the past tense:
appalled
Both varieties use this spelling.
If you are unsure about the base form, ask yourself whether you are writing British or American English.
Real-Life Logic
Imagine you are writing for a newspaper in London.
You might write:
The decision appalled local residents.
If you are writing for a newspaper in New York, you might write:
The decision appalled local residents.
In this example, you cannot see the difference because the past form is the same.
But in a dictionary entry or a sentence using the base form, the regional spelling becomes visible.
For example:
Such behavior can appal many people. — British spelling
Such behavior can appall many people. — American spelling
The meaning remains unchanged.
Daily Life Examples
1. Talking About Bad Behavior
A: Did you hear what he said to the waiter?
B: Yes. His behavior really appalled me.
The speaker thinks the behavior was extremely rude.
2. Talking About a News Story
A: Did you read the news this morning?
B: I did. The story appalled everyone at work.
Here, the story caused a strong emotional response.
3. Talking About Animal Treatment
A: Have you seen those pictures?
B: Yes. The way the animals were treated appalled me.
This is a natural context for the verb because cruelty can cause horror and disgust.
4. Talking About a Workplace
A: What did you think of the office conditions?
B: Honestly, they were appalling.
Here, appalling describes the conditions.
5. Talking About a School Decision
The parents were appalled by the sudden change in school fees.
This sentence describes the parents’ reaction.
6. Talking About Food Waste
It appals me when restaurants throw away perfectly good food.
The speaker feels strongly upset by the action.
In American English, the base form would normally be:
It appalls me when restaurants throw away perfectly good food.
7. Talking About a Movie
The final scene was so disturbing that it appalled some viewers.
The movie caused a strong emotional response.
8. Talking About a Mistake
The manager was appalled by the serious mistake.
The manager felt shocked and upset.
9. Talking About a Public Problem
The poor condition of the roads appalled the visitors.
The visitors thought the conditions were extremely bad.
10. Talking About a Personal Reaction
I was appalled at how much money was wasted.
This is a common everyday structure.
These examples show an important lesson: although appal and appall may look different, their normal sentence patterns are the same.
Appal vs Appall in British and American English
The spelling difference becomes much easier when you understand regional English.
British English often prefers shorter forms in some words that American English spells with a double l.
For this verb:
British English: appal
American English: appall
This does not mean that British speakers never encounter appall or that Americans cannot recognize appal. English is a global language, and people read material from many countries.
You may see both spellings online.
For an English-learning website, it is useful to explain both rather than labeling one as “wrong.”
If You Are Writing in British English
Choose:
appal
Examples:
The news may appal many readers.
Such behavior can appal the public.
If You Are Writing in American English
Choose:
appall
Examples:
The news may appall many readers.
Such behavior can appall the public.
What About Other Forms?
The interesting part is that the other forms are generally the same:
- appalled
- appalling
So the spelling difference mainly affects the base form and forms directly based on it where the final l pattern matters.
This is why Appal vs Appall can feel confusing at first.
Appal vs Appall in Formal Writing
Both forms can appear in formal writing.
The verb is not slang.
It is suitable for:
- essays
- reports
- news writing
- formal emails
- academic discussion
- opinion writing
- serious conversations
For example:
The evidence of poor working conditions appalled the investigators.
That sentence has a formal tone.
However, the word can also appear in everyday conversation:
That price appalled me!
So the word itself is not limited to formal English.
The context determines how formal the sentence feels.
Stronger Than “Surprise”
It is important not to use the verb for every surprising event.
If your friend buys a new phone, you might say:
I was surprised by her new phone.
You normally would not say:
Her new phone appalled me.
That would suggest the phone caused horror, disgust, or deep dismay.
Therefore, when learning Appal vs Appall, do not focus only on spelling. Learn the strength of the meaning too.
Appalled vs Appalling
This is one of the most important related grammar points.
Appalled usually describes how a person feels.
Appalling usually describes something that causes a very strong negative reaction.
Compare These Sentences
I was appalled by the news.
The person feels shocked.
The news was appalling.
The news itself was shocking or horrible.
Another example:
She was appalled by the rude comment.
The rude comment was appalling.
This distinction is similar to other adjective pairs such as:
- bored / boring
- excited / exciting
- shocked / shocking
- frightened / frightening
For learners, this is a very useful pattern.
Appal/Appall With Prepositions
The verb can appear with several useful structures.
Appalled by
We were appalled by the decision.
This is extremely common.
Appalled at
She was appalled at the amount of waste.
This is also common.
Appalled by the behavior
I was appalled by his behavior.
Appalled at the news
They were appalled at the news.
The choice between by and at can depend on the sentence and regional preference. Learners should focus first on the common patterns rather than trying to memorize a complicated rule.
Negative Meaning and Emotional Strength
The verb is normally negative.
It communicates a strong reaction such as:
- horror
- disgust
- shock
- dismay
- moral outrage
For example:
The cruel act appalled the community.
The community did not simply notice the act. People had a powerful negative reaction.
Because of this strong meaning, avoid using it for small problems.
Weak context:
I was appalled because my coffee was slightly cold.
Possible in a humorous or dramatic context, but not the normal serious use.
More natural serious context:
I was appalled by the way the workers were treated.
The second sentence fits the word much better.

Appal vs Appall: Quick Summary

- Appal is mainly the British spelling.
- Appall is mainly the American spelling.
- Both are verbs.
- Both have the same basic meaning.
- Both describe a strong negative emotional reaction.
- Appalled describes how someone feels.
- Appalling describes something that causes a strong negative reaction.

- Consistency matters when choosing British or American spelling.
The most important rule is simple:
British English → appal
American English → appall
Once you remember that, the spelling becomes much easier.
Why the Double “L” Can Be Confusing
English spelling is not always as predictable as learners would like.
Students often expect one spelling rule to work everywhere. Unfortunately, English has developed through many influences, including older forms of English and differences between regional varieties.
The word in question is a good example.
The British spelling uses:
appal
The American spelling uses:
appall
But when you change the word into the past tense, both use:
appalled
That can make learners wonder whether they have made a mistake.
They have not.
The spelling difference belongs to the standard forms of the two varieties.
This is also why memorizing the word as a complete vocabulary item can be more useful than trying to create a complicated rule.
How to Choose the Right Spelling
When deciding between the two forms, ask yourself three questions.
Question 1: Who Will Read My Writing?
If your readers are mainly in the United Kingdom, British spelling may be expected.
Use:
appal
If your readers are mainly in the United States, American spelling is usually more appropriate.
Use:
appall
Question 2: What Style Does My Website Use?
If your website already uses British spelling such as colour, favour, and centre, then appal will fit that style.
If it uses American spellings such as color, favor, and center, then appall is a natural match.
Question 3: Am I Being Consistent?
Consistency is more important than trying to prove that one spelling is universally correct.
A reader can understand both forms, but a consistent writing style looks more professional.
Pronunciation of Appal and Appall
Another interesting point in Appal vs Appall is pronunciation.
In normal English speech, the two forms are pronounced essentially the same.
The extra l in the American spelling does not create a completely different sound.
This means you cannot normally rely on pronunciation to decide which spelling someone is using.
That is why spelling knowledge matters.
If you hear someone say the word, you need the context to know whether they would write appal or appall.
The past form appalled is also pronounced in the same basic way regardless of whether the writer follows British or American spelling.
Word Family
Learning the word family can make vocabulary easier.
The main forms include:
Appal / Appall — base verb
Appals / Appalls — third-person singular
Appalled — past tense and past participle
Appalling — present participle/adjective
Examples:
The story appals many people.
The story appalls many people.
The story appalled many people.
The story was appalling.
Notice how the regional difference is most obvious in the base form and third-person form.
This word family is worth practicing as a group.
A Classroom Explanation
Imagine a teacher writing two sentences on the board:
The news may appal readers.
The news may appall readers.
A student asks, “Teacher, which one is correct?”
The best answer is:
Both are correct.
The first follows the spelling commonly used in British English.
The second follows the spelling commonly used in American English.
The teacher might then write:
The news appalled readers.
Now the student can see that the past tense looks the same.
This simple classroom example captures the main lesson of Appal vs Appall without making the topic unnecessarily difficult.
A Final Comparison With Similar Spelling Differences
English learners will eventually meet many spelling pairs that vary between British and American English.
For example:
| British English | American English |
|---|---|
| colour | color |
| favour | favor |
| centre | center |
| travelling | traveling |
| enrol | enroll |
| appal | appall |
These differences do not usually mean that the words have different meanings.
They reflect different spelling traditions.
So when you see Appal vs Appall, think of it as a regional spelling issue rather than a vocabulary issue.
That small change in thinking can remove a lot of confusion.
Final Tips for Students
If you want to remember this lesson for a long time, keep these four tips in mind.
First, learn the meaning before worrying about spelling. The word means to shock or horrify someone.
Second, connect appal with British English.
Third, connect appall with American English.
Fourth, remember that appalled and appalling are the forms you will often see in actual sentences.
Do not panic when you see the other spelling online. English is used around the world, and different regions have different spelling preferences.
If you are writing for a particular audience, follow that audience’s standard.
Conclusion
The key lesson from Appal vs Appall is quite simple: the two forms have the same basic meaning, but their spelling is usually linked to different English varieties.
Appal is the spelling commonly preferred in British English, while appall is generally preferred in American English. Both mean to shock, horrify, or deeply upset someone.
The grammar is also straightforward. Both forms work as verbs, and the related forms appalled and appalling are especially useful in everyday English. Remember that a person can be appalled, while something can be appalling.
You do not need to memorize a long list of complicated rules. Just remember the regional spelling difference and stay consistent in your writing.
When you read both forms, do not assume that one is a mistake. Understanding regional English will make your reading and writing much more confident.
A little practice with real sentences is usually enough to make the distinction feel natural.
