Opened is the correct spelling in both American and British English. Openned is a common spelling mistake, but the final “n” in open is never doubled before adding -ed. Once you understand this simple rule, choosing the right form becomes easy.
Quick Answer: Opened or Openned?
- Opened: Correct spelling and the past tense of open.
- Openned: Incorrect spelling and not a standard English word.
- Opening: Correct form used for an ongoing action.
- Openning: Incorrect spelling.
What Does Opened Mean?
Opened is the past tense and past participle of the verb open. It describes moving something from a closed position or making it accessible. It can also refer to starting a business or beginning an event.
For example, “She opened the door” describes allowing someone to enter. “The company opened a new branch” means the business started operating at another location.
Why Is Opened Spelled With One N?
English has a consonant-doubling rule for certain verbs before adding -ed or -ing. The final consonant is commonly doubled in a short verb when it follows a single vowel, as in stop → stopped and plan → planned.
However, open has two syllables, with stress on the first: O-pen. Because the final syllable is unstressed, the “n” stays single when adding a suffix.
- Open + ed = Opened
- Open + ing = Opening
Therefore, openned and openning are incorrect.
Opened in American and British English
There is no spelling difference between American and British English. Both use opened with one “n.”
American English: The store opened early on Monday.
British English: The museum opened a new exhibition last week.
Neither variety accepts openned as a standard spelling.
