When choosing between “openned” and “opened,” the correct spelling is opened. “Openned” is a misspelling and should not be used in standard English. The word opened is the past tense and past participle of the verb open.
This spelling can be confusing because many English verbs double their final consonant before adding -ed, such as stopped or planned. However, open does not follow that pattern. You write open → opened, not open → openned. Understanding this simple spelling rule can help students, ESL learners, and anyone writing English avoid a very common mistake.
Quick Answer
Opened is the correct spelling, while openned is incorrect. The verb open becomes opened in the past tense and past participle. For example: “She opened the door.” Do not double the final n when adding -ed to open.
Why Do People Confuse “Openned” and “Opened”?
The confusion usually comes from English spelling patterns involving verbs that end in a consonant.
Some short verbs double their final consonant before -ed:
- stop → stopped
- plan → planned
- rob → robbed
- shop → shopped
Because open ends in n, learners may assume that the same rule applies:
- open → openned
- open → opened
However, the spelling rule depends on the structure and pronunciation of the word. Open does not require the final consonant to be doubled.
