If you are unsure whether to write posible or possible, the correct English spelling is possible.
The difference is only one letter, but that extra s matters. In standard English, possible is the accepted spelling. Posible is generally a spelling mistake when you are writing in English.
The word possible is common in everyday American English. You can use it when something can happen, can be done, can exist, or may be true. For example, you might say, “Is it possible to finish this today?” or “It is possible that she will arrive later.”
The confusion often happens because possible contains two consecutive s letters. When people type quickly, they may accidentally leave one out. The spelling can also be confused with similar forms in other languages.
The good news is that the English choice is simple: use possible with two s’s.
Quick Answer
Possible is the correct spelling in standard English.
Posible is normally incorrect in English.
The word possible means that something can happen, can be achieved, can exist, or may be true.
Correct
- Is it possible to change the appointment?
- We need to find a possible solution.
- It is possible that he forgot.
- Please arrive as early as possible.
- Anything is possible with enough preparation.
Incorrect
- Is it posible to change the appointment?
- We need to find a posible solution.
- It is posible that he forgot.
The easiest way to remember the spelling is:
possible = poss + ible
Remember the two s letters in the middle.
Why People Confuse Them
The main reason people confuse posible and possible is that the two spellings look almost identical.
When someone types quickly, the second s can be easy to miss. This is especially common in informal messages, comments, notes, and other situations where people do not carefully check every word.
Pronunciation can also make the spelling less obvious. In American English, possible is commonly pronounced approximately like PAH-suh-buhl. The two written s letters do not sound like two separate sounds, so hearing the word does not necessarily remind you to write both letters.
Another source of confusion is the existence of similar-looking words in other languages. For example, Spanish uses posible for the corresponding word. That spelling can sometimes influence English writing, especially for bilingual speakers or people learning English.
However, when the sentence is written in English, the standard spelling is possible.
This is therefore not a difference in English meaning. There is no standard English distinction where posible means one thing and possible means another. The important difference is that possible is the standard English form.
Key Differences At A Glance
| Feature | Posible | Possible |
|---|---|---|
| Standard English spelling | No | Yes |
| Used as a normal English word | No | Yes |
| Meaning in standard English | Not a standard spelling | Can happen, exist, or be achieved |
| Correct for US English | No | Yes |
| Common mistake | Yes | No |
| Example | Incorrect: “It is posible.” | Correct: “It is possible.” |
The central point is simple: possible is the form you should use in standard American English.
Meaning and Usage Difference
Because posible is not the standard English spelling, it does not have a separate English meaning that contrasts with possible.
Possible, on the other hand, has several closely related uses.
First, it can describe something that can be done or achieved.
For example:
- Is it possible to finish the project today?
- We need to make the best decision possible.
- It may be possible to repair the computer.
- Can you arrive as soon as possible?
Second, possible can describe something that might happen or might be true.
For example:
- It is possible that the meeting will be canceled.
- A storm is possible this evening.
- There are several possible explanations.
- It is possible that she misunderstood the message.
Third, possible can describe something that can exist or occur.
For example:
- Scientists are considering possible explanations.
- We discussed every possible outcome.
- The team examined all possible options.
In each case, the spelling remains the same: possible.
A useful distinction is between possible and certain. Something possible may happen, but it is not guaranteed to happen.
For example:
It is possible that Jake will come.
This means Jake might come, but the speaker does not know for certain.
The spelling posible does not create another level of certainty. It is simply the wrong spelling for standard English.
Tone, Context, and Formality
There is no meaningful difference in tone or formality between posible and possible in standard English because only possible is the normal English form.
Possible works in almost every type of English writing.
Is it possible for you to call me later?
The experiment produced several possible explanations.
Please send the completed form as soon as possible.
You can also use it in formal writing:
Researchers considered several possible causes of the change.
The spelling does not change depending on the situation.
Whether you are writing a text message, email, essay, report, application, or professional document, write possible.
Using posible in an English sentence can make the writing look like it contains a spelling error.
Which One Should You Use?
Use possible whenever you are writing in English.
A simple rule is:
If the sentence is in English, spell the word possible with two s’s.
For example:
- It is possible to reschedule the meeting.
- We looked at every possible option.
- Is that possible?
- She wants to finish as quickly as possible.
- There is a possible explanation for the problem.
Avoid writing:
- It is posible to reschedule the meeting.
- We looked at every posible option.
- Is that posible?
If you are proofreading your writing, search for posible and replace it with possible whenever you are using the English word.
This is especially useful when editing schoolwork, business emails, website content, applications, or other important documents.
When One Choice Sounds Wrong
The word possible sounds normal in standard English because it is the established English form.
Posible may look understandable because it differs by only one letter, but it does not function as the standard English spelling.
Consider these examples:
Is it posible to get a refund?
The intended meaning is clear, but the spelling is incorrect.
The corrected version is:
Is it possible to get a refund?
Another example:
We need to consider every posible outcome.
The corrected sentence is:
We need to consider every possible outcome.
One more example:
It is posible that the store will close early.
Correct:
It is possible that the store will close early.
Notice that the sentence structure does not need to change. Only the spelling needs to be corrected.
This is an important point for English learners: posible is not a different English word that requires a different sentence pattern. In ordinary English writing, it is simply a misspelling of possible.
Common Mistakes (and Quick Fixes)
Mistake 1: Leaving out the second s
Incorrect:
It is posible to solve the problem.
Correct:
It is possible to solve the problem.
The most common correction is simply adding the missing s.
Mistake 2: Writing the word from memory
Some writers remember the sound of the word but not its exact spelling. Because the second s is not strongly noticeable when the word is spoken, they may write posible.
A helpful memory trick is to divide the spelling:
poss + ible = possible
The double s comes before ible.
Mistake 3: Confusing spelling with pronunciation
The word may sound like it has only one obvious s sound, but English spelling does not always correspond to individual sounds in a simple one-to-one way.
Do not use pronunciation alone to decide whether the word needs one or two s letters.
Remember the written form:
possible
Mistake 4: Assuming both forms are English variants
They are not standard spelling variants in English.
You should not treat posible as an alternative spelling of possible in ordinary American English writing.
Mistake 5: Using the wrong form in professional writing
A typo in a casual text may not matter much, but spelling mistakes can be more noticeable in resumes, reports, school assignments, business emails, and published content.
Before submitting important writing, check for posible and change it to possible.
Everyday Examples
Here are natural examples showing how possible is used in American English.
Example 1: Asking whether something can happen
Is it possible to meet tomorrow afternoon?
Here, possible means that the meeting can happen.
Example 2: Asking whether something can be done
Is it possible to finish the work by Friday?
The word describes whether completing the work can be achieved.
Example 3: Describing uncertainty
It is possible that the package will arrive tomorrow.
The sentence says that tomorrow’s arrival might happen, but it is not certain.
Example 4: Talking about choices
We discussed every possible solution.
Here, possible describes solutions that could potentially work.
Example 5: Talking about the maximum effort
Please reply as soon as possible.
This common expression means to reply at the earliest practical time.
Example 6: Talking about an outcome
We need to prepare for every possible outcome.
The phrase refers to outcomes that could happen.
Example 7: Talking about availability
Let me know if a different time is possible.
Here, possible describes whether another time can be arranged.
Example 8: Correcting the common mistake
Incorrect:
Is it posible to order this online?
Correct:
Is it possible to order this online?
Example 9: Workplace writing
Please send the updated document as soon as possible.
The spelling remains possible even in formal workplace communication.
Example 10: School writing
The researchers considered several possible explanations.
Again, possible is the correct form.
Dictionary-Style Word Details
Verb
Posible: Not commonly used as a verb in standard US English. It is not the standard English spelling of the word being discussed.
Possible: Not commonly used as a verb in standard US English. Possible is normally used as an adjective.
For example:
It is possible to complete the assignment today.
Here, possible describes whether completing the assignment can happen.
The related verb depends on the intended meaning. You should not turn possible into a verb simply because it describes something that can happen.
Noun
Posible: Not a standard English noun in this spelling.
Possible: The normal everyday use of possible is as an adjective, not a noun.
The related noun is possibility.
For example:
There is a possibility that the flight will be delayed.
The adjective is:
A delay is possible.
This distinction is useful because learners sometimes try to use possible where a noun is required.
Synonyms
Posible: No standard English synonym is needed because this spelling is not the standard English form.
Possible: Depending on the sentence, close alternatives can include achievable, feasible, conceivable, or potential. These words are not interchangeable in every sentence.
For example:
It is possible to finish today.
A suitable alternative in some contexts might be:
It is feasible to finish today.
However, feasible often focuses more specifically on practicality or practicality under the circumstances.
For uncertainty:
It is possible that she forgot.
Words such as conceivable may sometimes express a similar idea, but the meaning and tone can differ.
The safest choice when you simply mean that something can happen, exist, or be done is possible.
An obvious opposite is impossible.
For example:
It is possible.
versus:
It is impossible.
Example Sentences
Here are additional examples using the correct English spelling:

In every example, the correct spelling contains two s letters:
possible
Word History
The English word possible has a long history in English and is related to words that entered English through French and ultimately trace back to Latin. The modern English spelling is well established.
For everyday writing, however, you do not need to know the complete historical development to remember the spelling.
The practical point is that possible is the established English form.
The spelling posible should not be treated as an accepted alternative English spelling simply because it resembles the word in another language.
When writing standard American English, use:
possible
If you encounter posible in an English sentence, the safest assumption is that the writer intended possible.
