Have you ever typed posible and wondered if it was correct? You’re not alone. This is one of the most common English spelling mistakes because the two words look almost identical.
The only difference is one extra s, yet that single letter completely changes whether the word is correct or not.
The mistake appears in emails, essays, business documents, online forms, social media posts, and everyday messages.
While most spell-check tools can identify it, learning the correct spelling helps you write with greater confidence and accuracy.
The answer is simple: possible is the correct spelling, while posible is a common misspelling. Understanding why this mistake happens makes it much easier to avoid in the future.

Possible vs Posible
Many people search for posible or possible because they are unsure whether the word should contain one s or two.
The answer is straightforward.
| Feature | Possible | Posible |
|---|---|---|
| Correct spelling | ✅ Yes | ❌ No |
| Found in dictionaries | ✅ Yes | ❌ No |
| Accepted in academic writing | ✅ Yes | ❌ No |

Why Do People Write “Posible”?
Most people do not spell possible incorrectly on purpose. The mistake usually happens because of pronunciation, typing habits, or confusion with English spelling patterns.
The Double “S” Is Easy to Miss
When people pronounce possible, the double ss sounds almost the same as a single s. Because of this, many writers accidentally remove one letter and write posible.
Fast Typing
Typing quickly is another common reason. Missing one letter is a small error, but it changes the spelling completely.
Similar-Looking English Words
English contains words with one s and others with two.
For example:
- possible
- impossible
- necessary
- message
- discussion
Without remembering the correct spelling, it is easy to type posible instead.
Why “Possible” Is the Correct Spelling
Every major English dictionary lists only one accepted spelling:
- Possible
The spelling is used consistently in:
- Academic writing
- Business communication
- Books
- Newspapers
- Government documents
- Professional emails
- Websites
Whether you’re writing an essay, report, email, or blog post, possible is always the correct choice.
Is the Spelling Different in British and American English?

| English Variety | Correct Spelling |
|---|---|
| American English | Possible |
| British English | Possible |
| Canadian English | Possible |

No matter who your audience is, possible is the only correct spelling.

Word Origin
The word possible comes from the Latin word possibilis, which means able to be done or capable of happening. It later entered English through Old French and has kept the spelling possible ever since.
This is why possible is the standard spelling, while posible has never been accepted in English dictionaries.
Common Spelling Mistakes
The misspelling posible is common because the double ss is not strongly pronounced. As a result, many people accidentally remove one s while writing.
Other spelling mistakes also appear from time to time.
| Incorrect Spelling | Why It Happens | Correct Spelling |
|---|---|---|
| Posible | One s is omitted because the double ss sounds like a single s. | ✅ Possible |
| Possable | The ending -ible is confused with -able. | ✅ Possible |
| Possibel | The last two letters are typed in the wrong order. | ✅ Possible |
| Possibble | An extra b is added while typing quickly. | ✅ Possible |
None of these spellings are correct. If you notice them while proofreading, replace them with possible.
Easy Ways to Remember the Correct Spelling
Remember that possible has two “s” letters.
Think of this pattern:
Possible = Pos + sible
Another easy trick is to connect it with impossible.
- Possible ✅
- Impossible ✅
Since both words belong to the same word family, they both keep the double ss.
