Have you ever wondered whether the past tense of open is spelled opened or openned? You are not alone. This is a common spelling mistake, especially for English learners who assume that a final consonant should be doubled before adding -ed.
The correct spelling is opened. Openned is incorrect in standard English. The verb open becomes opened in the past tense and past participle because the final n is not doubled.
Understanding this simple spelling rule can help you avoid mistakes in emails, essays, assignments, messages, and everyday writing. In this guide, we will explain why opened is correct, why openned is wrong, and how to remember the difference easily.
Quick Answer
Opened is the correct spelling, while openned is incorrect. The verb open forms its past tense and past participle by adding -ed: open → opened. You do not double the final n. For example, “She opened the door” is correct.
Why Do People Confuse It?
The confusion usually comes from English spelling rules about doubling the final consonant before adding -ed.
For some short verbs, the final consonant is doubled:
- stop → stopped
- plan → planned
- drop → dropped
- rob → robbed
Because these words double their final consonant, it can seem logical to write openned.
However, open does not follow that pattern. Its final n stays single:
open + ed = opened
The difference becomes easier to understand when you look at the pronunciation and structure of the word.
First Word: Opened
