You are typing an important email and you stop mid-sentence. Should it be opening or openning? That extra “n” keeps nagging at you. You are not alone — this is one of the most searched spelling questions in English. The good news? The answer is short and clear.
“Opening” is the correct spelling. “Openning” does not exist in English.
This guide breaks down the rule behind the spelling, why people get it wrong, real-world examples, and a simple trick so you never mix them up again.
Openning or Opening – Quick Answer

Quick Comparison
| Spelling | Correct? | Use It? |
|---|---|---|
| Opening | ✅ Yes | Always |
| Openning | ❌ No | Never |
What Does “Opening” Mean?
The word opening is flexible. It works as a noun, an adjective, and part of a verb phrase. Here are its core meanings:
- A gap or space — There was an opening in the fence.
- The beginning of something — The opening chapter introduced the hero.
- An event launch — The grand opening drew a large crowd.
- A job vacancy — We have an opening in our sales team.
- An opportunity — She spotted an opening to make her point.
Because it covers so many situations — from business emails to creative writing — getting the spelling right matters every single time you use it.
Is “Openning” a Correct Word?
No. “Openning” is not a word in English. It never appears in any standard dictionary — not Merriam-Webster, not the Oxford English Dictionary, not Cambridge. It is purely a spelling error caused by misapplying a common grammar rule.
If your spell-checker flags “openning,” that red underline is correct. Delete the extra “n” and move on.
The Origin of Opening
The word traces back to Old English, where the verb was openian and the noun form was openung. Notice something? Even in Old English, there was no double “n.”
When modern English developed, the base verb stayed as open and the gerund/present participle became opening — one “n,” just as it always was.
Why “Opening” (Not Openning)?
English inherited this word with a single “n” and the spelling rules that apply to it have never changed. The root word open has two syllables, with stress on the first one (O-pen). That stress pattern is the key to the whole spelling question.
English Spelling Rule Behind Opening
This is the rule that settles the debate once and for all.
Why the Final “n” Is Not Doubled
In English, when you add -ing to a verb, you double the final consonant only when:
- The verb ends in a single vowel followed by a single consonant, AND
- The stress falls on the last syllable
The verb open ends in a vowel-consonant pattern (e-n), but the stress falls on the first syllable (O-pen), not the last. So the rule for doubling does not apply. You simply add -ing to get opening.
Common Verb + -ing Spelling Patterns
| Base Verb | Stress Syllable | -ing Form | Double Letter? |
|---|---|---|---|
| run | last (run) | running | ✅ Yes |
| sit | last (sit) | sitting | ✅ Yes |
| plan | last (plan) | planning | ✅ Yes |
| open | first (O-pen) | opening | ❌ No |
| listen | first (LIS-ten) | listening | ❌ No |
| happen | first (HAP-pen) | happening | ❌ No |
The pattern is clear. Multi-syllable verbs stressed on the first syllable — like open, listen, and happen — never double their final consonant before -ing.
Spelling Rule (British vs American English)
Key Point
There is no difference between British and American English on this word. Both spell it opening — one “n,” no exceptions.
This is worth noting because some spelling differences do exist between the two dialects (like colour vs color, or travelling vs traveling). Opening is not one of them. The rule is universal.
Comparison Table
| English Variety | Correct Spelling | Incorrect Spelling |
|---|---|---|
| American English | opening | openning |
| British English | opening | openning |
| Australian English | opening | openning |
| Global Standard | opening | openning |
Regardless of where you learned English or which style guide you follow, opening with one “n” is always right.
Which Spelling Should You Use?
Simple Answer
Use opening. Always. In every context. There is no situation where “openning” is acceptable.
Use “Opening” In:
- Formal essays and academic writing
- Business emails and professional documents
- Social media captions and blog posts
- Text messages and casual conversation
- Resumes and cover letters
- News articles and journalism
Never Use: “Openning”
“Openning” is incorrect in every context — formal, informal, British, American, digital, or printed. It is not a variant spelling, a regional form, or an acceptable alternative. It is simply a mistake.
Common Mistakes with Opening
Mistake 1: Adding an Extra “n”
The most frequent error is writing openning instead of opening. Writers often do this on autopilot, especially when typing quickly.
Wrong: The openning of the store is tomorrow. Right: The opening of the store is tomorrow.
Mistake 2: Confusing Pronunciation with Spelling
Some people hear the word spoken quickly and think the “n” sound is stronger than it is, leading them to write two. But pronunciation does not change spelling rules.
Mistake 3: Applying the Wrong Doubling Rule
Writers who know that run → running and begin → beginning sometimes apply the same logic to open. The key difference is syllable stress. Open is stressed on the first syllable, so the rule does not apply.
Mistake 4: Copying Common Online Typos
Online content — especially on social media, comment sections, and informal blogs — sometimes contains “openning” as a typo. Seeing it repeatedly can make it look familiar and even correct. It is not. Always verify with a dictionary.

Easy Trick to Remember the Correct Spelling
Here is the simplest memory trick you will ever need:
OPEN + ING = OPENING
Just visualize the word open and attach -ing to the end. No changes. No doubling. No extra letters. The base word stays completely intact.
Another way to think about it: words like open, happen, and listen all follow the same pattern — first-syllable stress, no doubling. If you can spell happening and listening, you can spell opening.

Frequently Asked Questions
Is “openning” ever correct?
No. Openning is always a spelling mistake. There is no context, dialect, or style guide in which it is accepted.
Why do people write “openning” instead of “opening”?
Because English does double consonants in words like running and planning, people incorrectly apply the same rule to open. The difference is syllable stress — open is stressed on the first syllable, so no doubling occurs.
Can “opening” be both a noun and a verb?
Yes. It functions as a noun (the opening of the event), an adjective (the opening chapter), and as part of a verb phrase (she is opening the window).
Is “opening” spelled differently in British and American English?
No. Both British and American English spell it the same way: opening.
What is the origin of the word “opening”?
It comes from Old English openian (the verb) and openung (the noun form). Neither the old form nor the modern one has a double “n.”
How do I remember the correct spelling?
Think of it as open + ing. The base word does not change. Just add -ing directly and you are done.
Is “opening” used in formal writing?
Absolutely. It is used in legal documents, academic papers, business communications, journalism, and literature — always spelled with a single “n.”
Final Verdict: Opening or Openning?
The answer could not be clearer: opening is correct, and openning is always wrong.
The confusion comes from a genuine misunderstanding of English consonant-doubling rules. Once you understand that doubling only happens when the stress falls on the last syllable — and that open is stressed on the first — the correct spelling becomes obvious and unforgettable.
Whether you are writing a formal report, crafting a business email, posting on social media, or typing a quick text, the rule is the same every single time: one “n,” not two. Use opening with confidence, and leave openning behind for good.
