English spelling can be confusing, especially when past-tense verbs are involved. One of the most common questions people ask online is “opened or openned – which one is correct?” This confusion usually appears while writing emails, assignments, news content, or social media posts.

Opened or Openned – Quick Answer
Opened is the only correct spelling.
Openned is incorrect and not accepted in English.
Examples
✅ She opened the door quietly.
✅ The shop opened at 9 a.m.
❌ She openned the door.
Rule: The verb open does not double the final consonant when adding -ed.
The Origin of Opened or Openned
The word open comes from Old English openian, meaning “to make open.” Over time, it stayed simple in structure and pronunciation. When English verbs form the past tense, they usually add -ed.
However, consonant doubling follows a specific rule:
A final consonant is doubled only if the verb ends in one vowel + one consonant, and the stress is on the last syllable.
Examples:
- stop → stopped
- plan → planned
But open does not meet these conditions:
- It ends with two syllables (o-pen)
- The stress is on the first syllable
That’s why opened is correct and openned never existed as a standard form.
British English vs American English Spelling
Good news: There is no difference here.
Both British English and American English use opened only. The incorrect form openned is rejected in all major dictionaries, style guides, and grammar rules.
