The exact pronunciation can vary slightly depending on the speaker’s accent.
The spelling difference does not create a difference in meaning or pronunciation.

Appal vs Appall: American and British English
This is where the distinction becomes especially useful.
British English: appal
British English traditionally uses:
appal
For example:
The conditions at the facility appalled the inspectors.
American English: appall
American English generally uses:
appall
For example:
The conditions at the facility appalled the inspectors.
Notice something interesting: although the base forms differ, the past tense appalled is spelled the same in both varieties.
The same is true of appalling.
So the regional difference is most obvious in the base form:
British: appal
American: appall
Why Does Appal Have One “L”?
The difference comes from broader spelling conventions between British and American English.
American English often uses double l in words where British English uses a single l in certain forms.
Compare:
- appal → appall
- enrol → enroll
- fulfil → fulfill
- instil → instill
This pattern is not completely universal, so it is best to check individual words rather than assuming every British-American spelling follows exactly the same rule.
For appal/appall, however, the distinction is clear and widely recognized.
Common Mistakes with Appal and Appall
Mistake 1: Thinking one spelling is completely wrong
It is not correct to say that appal is simply a misspelling of appall, or vice versa.
Both are established spellings.
The correct choice depends largely on the variety of English you are using.
British English: appal
American English: appall
Mistake 2: Writing “appalled” differently
Because the base forms differ, some writers assume their past forms should also differ.
But both varieties use:
appalled
For example:
She was appalled by the decision.
This spelling works in both American and British English.
Mistake 3: Confusing “appal” with “appeal”
These words look somewhat similar but have completely different meanings.
Appal/appall means to shock or horrify.
Appeal can mean to attract, request something, or formally challenge a decision.
Compare:
The cruelty appalled him.
The idea appealed to him.
The first describes strong shock or horror, while the second describes attraction or approval.
Mistake 4: Using “appall” in British writing without considering style
Appall is not necessarily incomprehensible to British readers, but appal is the traditional British spelling.
If you are producing content specifically for a British audience, maintaining British spelling consistently is usually preferable.
