Have you ever typed “posible” and wondered if it looks right? You are not alone. This is one of the most common spelling mistakes in English, and even native speakers make it again and again.
Only one of these spellings is correct. Let us see which one — and why the wrong version keeps showing up.
First Things First: What Does “Posible” Mean?
“Posible” is not a correct English word — it is a misspelling of “possible”. No English dictionary lists it, and spellcheckers always mark it wrong.
“Posible” is simply a misspelled version of “possible” — it has no meaning of its own in English.
Interestingly, “posible” IS a real word in Spanish — one big reason Spanish speakers make this mistake in English.
Where You See Posible in Real Life
You will mostly run into “posible” in these places:
- Quick text messages and social media posts typed in a hurry
- Essays by English learners, especially Spanish speakers
- Online comments and forum discussions
- Spanish-language websites — where it is actually correct!
Why Posible Matters
- It is one of the most common English spelling errors in the world
- Teachers often circle it in red in student essays
- In formal writing, it makes the writer look careless
So when you see “posible” in English text, remember: it is a mistake, not a word.
Now, What Is “Possible”?
“Possible” is the correct spelling. It is an adjective that describes something that can happen, be done, or be achieved. It is one of the most useful and common words in English.
Something that can happen, be done, or be achieved.
It is the positive opposite of “impossible” — if something is possible, there is a way to make it real.
The Idea Behind Possible
- Ability: it describes what can be done — “It is possible to learn English.”
- Chance: it describes what might happen — “It is possible that she is busy.”
- Hope: it keeps the tone positive — “A better future is possible.”
- Options: it lists choices — “There are three possible answers.”
If something is possible, the door is open — it can happen.
Real-Life Example
Imagine your friend asks, “Can we finish this project by Friday?” You check the remaining work and answer:
- “Yes, it is possible if we start today.”
- You are saying the project can be finished
- You are giving a realistic but hopeful answer
Why People Confuse Posible and Possible
The confusion is easy to explain:
- “Posible” is the correct spelling in Spanish, so Spanish speakers naturally write it that way
- The single “s” sounds exactly the same as the double “s” when spoken aloud
- Fast typing often drops a letter without the writer noticing
Posible vs Possible: Side-by-Side Comparison
Here is the full picture in one simple table:
| Feature | Posible | Possible |
|---|---|---|
| Type | Misspelling (in English) | Correct English word |
| Meaning | No meaning in English | Something that can happen or be done |
| Usage | Never correct in English | Everyday writing and speech |
| Origin/Spelling | Missing one “s” | From Latin “possibilis” — always double “s” |
| Context | Typing errors, Spanish text | Essays, emails, conversations |
| Example | “Is it posible?” (wrong) | “Is it possible?” (right) |
How to Use “Posible” Correctly
You cannot use “posible” correctly in English — because it is not an English word. The only rules are:
- Never use “posible” in English writing
- Always write “possible” with two s’s
- If your spellchecker underlines “posible”, fix it immediately
- Remember: Spanish “posible” is not the same as English spelling
- When in doubt, think of “impossible” — it has two s’s too
Natural Examples
Here is what the corrected sentences look like:
- “Is it possible to finish today?”
- “They did everything possible to help.”
- “It is possible he forgot the meeting.”
Notice the double “s” every single time — that is the key.
How to Use “Possible” Correctly
Use “possible” when talking about:
- Things that can be done — “It is possible to learn a new skill.”
- Things that might happen — “It is possible that it will rain.”
- Choices and options — “We have two possible plans.”
- Hopeful situations — “Peace is possible.”
Natural Examples
- “Is it possible to get a refund?”
- “She did everything possible to win.”
- “It is possible they are still at work.”
Use it whenever something can happen or be achieved.
A Simple Trick to Remember the Difference
Here is an easy trick that never fails:
- Think of “impossible” — it also has a double “s”. If “impossible” has two s’s, “possible” must too.
- Say it slowly: pos-si-ble. Two “s” sounds, two “s” letters.
Two s’s = correct.
One “s” = mistake.
Where You Might See These Words Online
Posible (Common Usage)
- Spanish-language websites, where it is perfectly correct
- Unedited comments, chats, and quick posts
- Writing by English learners
Possible (Correct Usage)
- News articles, blogs, and books
- Job applications and formal emails
- Textbooks, exams, and academic papers
- Professional documents of every kind
Context matters: “posible” belongs to Spanish; “possible” belongs to English.
Interesting Fact You Probably Didn’t Know
“Possible” comes from the Latin word “possibilis”, which means “that can be done”. That double “s” has survived for more than 2,000 years — traveling from Latin, through French, and into English without losing a single letter.
The misspelling “posible” is much younger — born from fast typing and Spanish influence.

Common Mistakes to Avoid
Watch out for these typical errors:
❌ Writing “posible” in an English essay
Wrong: “It is posible to solve this problem.”
Right: “It is possible to solve this problem.”
❌ Copying the Spanish spelling into English
Wrong: “Posible in English, posible in Spanish — same thing.”
Right: “In English it is “possible”; in Spanish it is “posible”.”
❌ Forgetting the double “s” in a job application
Wrong: “I will do everything posible to succeed.”
Right: “I will do everything possible to succeed.”
In formal writing, this small mistake can make a surprisingly big difference.
Which One Should You Use?
The answer is clear:
- Writing in English? → Possible
- Writing in Spanish? → Posible
- Not sure which language? → Possible (with two s’s)
Final Thoughts
“Posible” and “possible” look almost identical, but only one is a real English word.
The double “s” is the whole secret. Keep it in mind, and you will never misspell this word again.
“One letter or two — which spelling will you choose next time?”
Choose “possible”, and always choose it with two s’s.
