Why Do People Write “Openned”?
This mistake usually occurs because writers try to apply other English spelling patterns incorrectly.
Similar Words That Double the Final Consonant
Examples:
- Plan → Planned
- Stop → Stopped
- Admit → Admitted
Because these words double the final consonant before adding -ed, some people assume open should become openned.
However, English spelling rules do not work that way for every verb.
Why “Opened” Is Correct
The verb open follows a different pattern.
Rule
When a verb ends with:
- A vowel + consonant pattern
- But the stress is not on the final syllable
The final consonant is usually not doubled.
Examples:
| Base Verb | Past Tense |
|---|---|
| Open | Opened |
| Visit | Visited |
| Listen | Listened |
| Happen | Happened |
| Enter | Entered |
Notice that none of these verbs double the final consonant.
Therefore:
- Open → Opened ✅
- Open → Openned ❌

Many writers repeat the same spelling errors.
Mistake 1: Writing Openned
Incorrect:
- I openned the email.
Correct:

Mistake 2: Doubling Consonants Automatically
Some people believe every verb ending in a consonant should double the letter before -ed.
This is not true.

- Entered
Incorrect:
- Openned
- Happenned
- Listenned
- Enterred
Mistake 3: Relying Only on Pronunciation
English spelling often differs from how words sound.
Because spoken English can make “opened” sound like it contains a doubled “n,” some writers mistakenly spell it as openned.
Always rely on standard spelling rules rather than pronunciation alone.
