Possible or Posible: Which Is Correct?

Updated 2026-10-12 · Which One Is Correct editorial team

Quick answer: When asking whether possible or posible is correct, the answer is clear: possible is the only correct spelling, while posible is a common misspelling. The word means capable of happening or being achieved, and it follows standard English spelling rules. Remember that the letter i appears after the s, never before it, ensuring the word is written with a double l and the correct vowel order. Using the correct form helps your writing appear professional and easy to understand for all readers.

The Short Answer

People often confuse these words because they sound identical and the letters are close on a keyboard. The error usually happens when typing the s or when the brain skips a letter during quick composition.
