“Opened” is the correct spelling. “Openned” is incorrect and doesn’t appear in any standard English dictionary. The mix-up happens because many English verbs double their final consonant before adding “-ed” — but “open” isn’t one of them, since the stress falls on its first syllable rather than its second. This guide covers the spelling rule, pronunciation, word forms, and common mistakes so you can use “opened” correctly every time.
Quick Answer: Opened Is Correct
| Spelling | Status | Notes |
|---|---|---|
| opened ✅ | Correct | Standard past tense and past participle of “open” |
| openned ❌ | Incorrect | Not recognized in any English dictionary |
Correct: She opened the store early today.
Incorrect: She openned the store early today.
The difference comes down to one rule: “open” never doubles its final “n” before “-ed,” even though many two-syllable verbs do.
What Does “Opened” Mean?
“Opened” is the simple past tense and past participle of the verb “open.” It describes something that changed from a closed, locked, or unavailable state to one where it could be accessed, entered, or used.
Most common meaning (verb): to move or unlock something so it no longer blocks access. Example: He opened the drawer and pulled out a notebook.
Second meaning (verb): to start or begin something, such as an event, meeting, or business. Example: The committee opened the meeting with a short update.
Adjective use: “Opened” can also describe a completed state, similar to “unlocked” or “unsealed.” Example: An opened bottle of wine should be finished within a few days.
Why Do People Write “Openned” Instead of “Opened”?
People write “openned” because they’re applying a spelling pattern that works for other short verbs but doesn’t apply to “open.” In English, when a one-syllable verb ends in a single vowel followed by a single consonant, the final consonant is often doubled before “-ed” — as in stop → stopped or plan → planned. For verbs with more than one syllable, that doubling only happens when the stress falls on the last syllable, as in begin → beginning or prefer → preferred. Because “open” looks like it could follow the same pattern, writers sometimes double the “n” by mistake.
The Spelling Rule Behind “Opened” (And Why It Applies Here)
“Open” is stressed on its first syllable — OH-pen, not oh-PEN — so its final consonant doesn’t double before “-ed.” This is the same reason “happened,” “listened,” and “visited” also keep a single consonant, while stress-on-the-last-syllable words like “begin” and “occur” double theirs.
| Word | Stress | Doubles before -ed/-ing? | Result |
|---|---|---|---|
| open | OH-pen (1st syllable) | No | opened, opening |
| begin | be-GIN (2nd syllable) | Yes | beginning |
| visit | VIS-it (1st syllable) | No | visited |
| occur | oc-CUR (2nd syllable) | Yes | occurred |
How to Pronounce “Opened” (With Syllable Breakdown)
“Opened” has two syllables, with the stress on the first one: OH-pend.
- US pronunciation: /ˈoʊpənd/
- UK pronunciation: /ˈəʊpənd/
The only difference between the two is the standard vowel shift found in many English words with “o” — American English uses a slightly more rounded “oh” sound, while British English uses a diphthong closer to “uh-oh.” The spelling and stress pattern are identical in both varieties.
Is “Opened” a Verb or an Adjective?
“Opened” can function as either a verb or an adjective, depending on the sentence.
- As a verb: She opened the window. / The store has opened for the season.
- As an adjective (describing a noun directly): an opened letter, an opened jar.
A quick way to tell the difference: if “opened” is performing the action or follows a helping verb like “has” or “have,” it’s a verb. If it sits directly in front of a noun to describe its state, it’s acting as an adjective.
Where Does “Opened” Come From? (Word Origin)
“Opened” comes from the Old English word “open,” which already meant “not closed.” Through Middle English, “open” descended from an earlier West Germanic root related to being “up” or “over” — the same root family that gave related Germanic languages their own words for “open.” The “-ed” ending was simply added later, following the regular pattern for forming the past tense of English verbs.

Incorrect: He openned the box. Correct: He opened the box. Explanation: Doubling the “n” is the most common error. “Open” never doubles its final consonant before “-ed.”

Incorrect: I have open the door already. Correct: I have opened the door already. Explanation: After “have,” “has,” or “had,” English requires the past participle “opened,” not the base form “open.”

Synonyms for “Opened”
The best synonym depends on context:
- Physical opening: unlocked, unfastened, unsealed
- Starting an event or business: launched, started, began
- Formal or figurative sense: unveiled, revealed, disclosed
These aren’t always interchangeable — “unveiled” fits a product launch, for instance, but would sound odd describing a door.
“Openned” vs “Openning”: Don’t Make Both Mistakes
“Openning” is also incorrect. The correct spelling is “opening,” for exactly the same reason “openned” is wrong — the final “n” in “open” is never doubled, whether you’re adding “-ed” or “-ing.”
Incorrect: The openning ceremony starts at noon. Correct: The opening ceremony starts at noon.

Frequently Asked Questions
Is “openned” ever correct in any variety of English?
No. “Openned” isn’t accepted in American, British, Australian, or any other standard variety of English. Only “opened” appears in dictionaries and style guides.
Why doesn’t “open” double its final “n” the way “stop” becomes “stopped”?
Because the stress in “open” falls on the first syllable, not the last. English generally only doubles the final consonant of multi-syllable verbs when the stress lands on that last syllable, as in “begin” → “beginning.”
Does “opened” change spelling between American and British English?
No. The spelling is identical in both. The only difference is a slight vowel shift in pronunciation.
Can “opened” function as an adjective?
Yes. Besides being a verb form, “opened” can describe a noun directly, as in “an opened can of paint.”
What’s the difference between “open” and “opened”?
“Open” is the base form, used as a present-tense verb or as an adjective describing a current state. “Opened” is the past tense and past participle, used for a completed action.
Is “openning” also incorrect, like “openned”?
Yes. The correct spelling is “opening.” Both mistakes come from the same false assumption that “open” doubles its final consonant.
Does spellcheck always catch “openned”?
Most modern spellcheckers flag it, but not always — especially in short messaging apps or tools without strong grammar checking.
How many syllables does “opened” have?
Two: “o” and “pened,” with the stress on the first syllable.
Is there a simple trick to remember the correct spelling?
As a learning aid, picture opening something with a single motion: one push, one “n.” Remember that open + ed = opened, with nothing doubled in between.
Are there other verbs that follow the same non-doubling pattern as “open”?
Yes. Verbs like “happen,” “listen,” and “visit” also keep a single final consonant before “-ed” because their stress falls on the first syllable: happened, listened, visited.
Getting “Opened” Right Every Time
“Opened” is the only correct spelling of the past tense and past participle of “open.” “Openned” is a common but incorrect form that comes from misapplying a doubling rule that doesn’t fit this word. Since “open” is stressed on its first syllable, the final “n” stays single before “-ed.” Keep the memory cue in mind — one push, one “n” — and you’ll spell it correctly every time.
