The One Real Difference Between Appal and Appall
The only difference between appal and appal is regional spelling.
There is no difference in meaning, pronunciation, grammar, tone, or level of formality. Both verbs describe causing someone to feel intense shock, horror, disgust, or deep dismay.
For example:
- The news appalled everyone in the office. (American English)
- The news appalled millions across the country. (American English)
- The news appalls many readers. (British English)
- The decision continues to appal local communities. (British English)
In every example, the emotional impact is identical. Only the preferred spelling changes according to regional English conventions.
Remember This Rule
- British English → appal
- American English → appall
That’s the only distinction most writers need to remember.
What Does “Appal” Mean?
Appal is the standard British English spelling of the verb to shock, horrify, or fill someone with deep dismay.
It commonly appears in British newspapers, academic writing, government publications, literature, and formal communication. Writers use appal when describing events or actions that provoke a strong emotional response rather than simple surprise.
Definition

British writers often use appal when discussing:
- Serious crimes
- War and conflict
- Political scandals
- Human rights abuses
- Natural disasters
- Cruel or unethical behavior
- Public outrage

Unlike words such as surprise or shock, appal usually suggests moral outrage, horror, or profound emotional distress.

Appall is the standard American English spelling of the verb to shock, horrify, or deeply upset someone. It appears in American dictionaries, newspapers, books, academic writing, legal documents, and professional communication.

Which Version Should You Use?
For most writers, choosing between appal and appal is simple: match the spelling to your audience.
If you’re writing for readers in the United States, use appall. If your audience is in the United Kingdom or follows British English conventions, use appal.
Whichever spelling you choose, use it consistently throughout your document. Mixing both forms in the same article can distract readers and make your writing look less polished.
Quick Rule

- Follow your organization’s style guide if one applies.
- Don’t switch spellings within the same document.
Editor’s Tip: If you’re unsure which variety of English to use, check your publication’s style guide or the spelling used elsewhere on the website.
Origins and Etymology
The history of appal and appal explains why two spellings exist for the same word.
Although modern English treats them as regional variants, both forms share the same origin and have developed together over centuries.
Historical Development
The word entered Middle English through Anglo-French, where it originally described turning pale because of fear or shock.
Over time, the literal meaning gradually evolved into the figurative sense we use today—causing someone to feel intense horror, disgust, or deep emotional distress.
Modern English speakers rarely associate the word with becoming pale, but that original image still reflects the powerful emotional reaction the verb describes.
Latin and French Roots
The word ultimately comes from the Latin verb pallere, meaning to be pale.
From Latin, it passed into Old French as apalir, meaning to become pale with fear.
English later adopted the term, and its meaning gradually shifted from a physical reaction to an emotional one.
This evolution explains why appal and appal describe a reaction so intense that it metaphorically causes someone to lose color in their face.
Why Two Spellings Exist
Before English spelling became standardized, writers often used different spellings for the same word.
As dictionaries and publishing conventions developed, regional preferences became more consistent.
British English settled on appal, while American English standardized appal.
Despite the spelling difference, the pronunciation, grammar, and meaning remained unchanged.
Regional Usage Around the English-Speaking World
Different English-speaking countries have adopted different spelling conventions. Knowing these preferences helps your writing feel natural to local readers.
United Kingdom
British English strongly prefers appal.
You’ll commonly find this spelling in:
- Newspapers
- Government publications
- Academic writing
- Literature
- Business communication
Examples: - The findings continue to appal environmental experts.
- The decision will appal many voters.
- Such behavior would appal any reasonable person.
United States
American English consistently favors appall.
Nearly all major U.S. dictionaries, universities, newspapers, and publishing houses recommend the double-l spelling.
Examples:
- The accident appalled the entire community.
- Rising costs continue to appall consumers.
- The report appalled lawmakers.
Canada
Canadian English combines British and American spelling traditions, but appall is more common in newspapers, academic writing, and government publications.
If you’re writing for a Canadian audience, appall is usually the safest choice.
Australia and New Zealand
Australian and New Zealand English traditionally follow British spelling, so appal remains the preferred form.
However, appall also appears in international publishing, especially in content intended for a global audience.
Other International English Varieties
Countries where British English is widely taught—such as India, Pakistan, South Africa, and Singapore—generally recognize appal as the standard spelling.
However, international companies and global websites often choose appall because it aligns with American English and reaches a broader audience.
Regional Preference Table
| Region | Preferred Spelling | Notes |
| United Kingdom | Appal | Standard British spelling |
| United States | Appall | Standard American spelling |
| Canada | Appall | Most common in formal writing |

- Criminal cases

Its concise meaning allows journalists to communicate emotional impact without lengthy explanation.
Creative Writing

- The condition of the building appalled visitors.
- Animal cruelty continues to appall millions of people.

Incorrect
- The report appalled readers, but later events continued to appalleveryone.

Appall is much stronger. It usually suggests moral outrage, horror, or disgust.

Alarm focuses on fear about possible danger or future consequences.
Appall describes an emotional reaction to something already considered shocking or unacceptable.

Writing Tips for English Learners
Choosing the right verb depends on both the situation and the emotional intensity you want to express.
Keep these practical tips in mind:
- Use appalled or appalled only for serious situations, not minor inconveniences.
- Match the spelling to your audience’s variety of English.
- Maintain the same spelling throughout your article, essay, or email.
- Prefer shock if the event is surprising but not deeply disturbing.
- Choose horrify when fear is the dominant emotion.
- Use appall when emphasizing moral outrage, disgust, or profound disapproval.
Pro Tip: In professional writing, overusing emotionally charged verbs can weaken your message. Reserve appall for situations that genuinely deserve such a strong reaction, and use milder alternatives like concern, upset, or surprise when appropriate.
Style Tips for Professional Writing
Choosing the correct spelling is only one part of effective writing. To make your English sound more natural and polished, pay attention to tone, audience, and context.
Match Your Audience
Before you start writing, decide which variety of English your readers expect.
- Writing for the United States? Use appall.
- Writing for the United Kingdom? Use appal.
- Writing for an international audience? Follow your organization’s style guide and stay consistent.
Avoid Overusing Strong Language
Because appal and appal express intense emotion, they work best for serious situations. Using them too often can make your writing sound exaggerated.
Instead of writing:
- The long meeting appalled the staff.
A more natural choice is: - The long meeting frustrated the staff.
Reserve appall for events involving genuine shock, horror, or moral outrage.
Choose Precise Alternatives When Needed
Sometimes another verb communicates your meaning more accurately.
| If You Mean… | Better Choice |
| Mild surprise | surprise |
| Concern | alarm |
| Disappointment | dismay |
| Sadness | distress |
| Extreme horror | appall or horrify |
| Using precise vocabulary improves both clarity and style. |

English learners preparing for academic or professional exams may encounter both spellings.
American English Exams
Tests that follow American English conventions, such as the TOEFL or many U.S.-based assessments, generally expect appall.
British English Exams

Exam Tip
If the exam follows one variety of English, keep your spelling consistent throughout your answers. Mixing British and American spellings may affect your score in writing tasks where consistency is assessed.
