Possible is the correct standard English spelling. Posible is a misspelling in standard English and should not be used in formal or everyday writing. The word possible is an adjective meaning that something can happen, exist, or be done. For example, “Is it possible to finish the project today?”
Quick Answer
If you are wondering whether to write posible or possible, use possible. It is the standard English spelling. The incorrect form posible is usually caused by forgetting the second s. The correct spelling contains two consecutive s letters: possible.
Remember: possible means something can happen or can be done. For example, “We will find the best possible solution.” In standard English, posible should be corrected to possible.
What Does Possible Mean?
Possible is an adjective used when something can happen, exist, be true, or be done. It can describe an opportunity, outcome, explanation, solution, event, or situation that is not impossible.
For example:
- Is it possible to complete this work today?
- There is a possible explanation for the problem.
- We are looking for the best possible solution.
- It is possible that she will arrive late.
The word can refer to something that is merely capable of happening, without saying that it definitely will happen.
What Does Posible Mean?
Posible is not the standard spelling of the English word. When someone writes posible in English and intends to mean “capable of happening or being done,” the correct spelling is possible.
The most common reason for this mistake is forgetting the second s. Because the word is pronounced naturally in connected speech, some writers may remember only one s when spelling it.
Correct:
It is possible to solve the problem.
Incorrect:
It is posible to solve the problem.
The Core Rule: Possible Has Two S’s

The easiest spelling rule to remember is simple: possible contains two consecutive s letters.
The correct spelling is:
P-O-S-S-I-B-L-E
Not:
P-O-S-I-B-L-E
When writing the word, mentally divide it into:
pos + sible → possible
The second s is essential to the standard spelling.

Why Do People Write Posible Instead of Possible?
The most common reason is a simple spelling omission. Writers may remember the sound of the word but fail to include both s letters when typing it.
Another reason is that possible is pronounced as a smooth sequence of sounds rather than as two clearly separated s sounds. This can make the second s easy to overlook when spelling from memory.
Typing quickly can also contribute to the error. Because posible looks visually similar to possible, the missing letter may go unnoticed during casual proofreading.
Common Mistakes With Possible
- Writing posible instead of possible.
- Forgetting the second s.
- Assuming pronunciation tells you the complete spelling.
- Typing too quickly and skipping a letter.
- Failing to proofread short, common words.
Possible in Real English

For example, someone might say, “Is it possible to meet tomorrow?” In professional writing, you might see, “Please provide the information as soon as possible.” In academic writing, a sentence might state, “Several possible explanations should be considered.”
The misspelling posible should be corrected in standard English writing.

Possible in Formal and Informal English
Possible is appropriate in both formal and informal English. There is no need to replace it with a different word simply because the context is professional.

The spelling remains the same in both contexts.
American vs British English

There is no significant American-versus-British spelling difference between possible and posible. Possible is the standard spelling in both American English and British English.
Therefore, changing from one English variety to another does not make posible correct.
Possible vs Posible: A Simple Memory Trick
Use this memory trick:
Possible has two S’s because it is possible to spell it with “SS.”
You can also remember the visual pattern:
POS + SIBLE = POSSIBLE
Whenever you are unsure, check whether your spelling contains ss. If it contains only one s, you have probably written the word incorrectly.
