Last week, a student typed an assignment question: “Is it posible to finish this project today?” A classmate quickly replied, “It’s spelled possible!” Suddenly, the discussion shifted from deadlines to spelling.
If you’ve ever wondered posible or possible, you’re not alone. Students, writers, ESL learners, and professionals frequently search this question because both versions appear online.
The confusion usually arises from pronunciation, typing errors, and the silent letters in English. People want to know which spelling is correct, how to use it properly, and why the double “s” exists in the correct form.
This guide will explain the difference between posible or possible, explore its origin, compare British and American English usage, highlight common mistakes, and provide real-world examples.
By the end, you’ll confidently know which spelling to use in essays, emails, reports, or casual writing.
Quick Answer
Possible is the correct spelling.
- Posible is a common misspelling and not recognized in standard dictionaries.
- Possible means something that can happen, be done, or be achieved.
Examples
- Correct: “Is it possible to complete this task today?”
- Incorrect: “Is it posible to complete this task today?”
Both sentences have the same intended meaning, but only one is correct in formal and casual writing.
The Origin of Posible or Possible
The word possible comes from the Latin possibilis, meaning “able to be done.”
- It entered English through Old French in the 14th century.
- Middle English retained the double “s,” which is why possible has two “s” letters today.
The spelling “posible” drops a letter and is considered a typographical or phonetic error. Dictionaries such as Merriam-Webster and Oxford English Dictionary list possible as the correct form, confirming that the other version is incorrect.
British English vs American English Spelling
Unlike some words with regional differences, possible is the same in both British and American English.
| Region | Correct Spelling | Notes |
|---|---|---|
| United States | possible | Standard in academic and business writing |
| United Kingdom | possible | Standard across formal and informal contexts |
| Commonwealth | possible | Same as UK usage |
There is no variation; the confusion usually comes from typing errors or informal communication.
Which Spelling Should You Use?
- Academic Writing: Always use possible. Essays, research papers, and assignments must follow dictionary rules.
- Business Writing: Possible is safe and professional in reports, emails, and proposals.
- Casual Writing: Even in texts or social media, use possible to avoid confusion.
The only acceptable spelling is possible. Avoid “posible” in every context.
Common Mistakes with Posible or Possible
- Missing a “s”
- Incorrect: “It’s posible to finish today.”
- Correct: “It’s possible to finish today.”
- Phonetic Typing
- Many people type what they hear, dropping the silent “s.”
- Confusing with other words
- Don’t mix possible with probable, feasible, or potential. Each word has distinct meaning.
