Have you ever typed occurring and wondered whether it should actually be spelled occuring? You’re not alone. This is a common spelling mistake because the word comes from occur, and doubling the final consonant before adding -ing can feel confusing.
The correct spelling is occurring with two r’s. Occuring is a misspelling and should not be used in standard English. In this guide, you’ll learn why the spelling is occurring, what the word means, how to use it correctly, and how to remember the difference easily.
Quick Answer:
Occurring is the correct spelling.
Occuring is incorrect.
| Word | Correct? | Meaning |
| Occurring | ✅ Yes | Happening or taking place |
| Occuring | ❌ No | Incorrect spelling of “occurring” |
Examples
- The meeting is occurring at noon.
- Scientists are studying the changes occurring in the environment.
- The problem keeps occurring despite our efforts.
- Several unusual events are occurring in the city.
If you’re writing an email, essay, article, report, or academic paper, always use occurring.
What Does “Occurring” Mean?
Occurring is the present participle of the verb occur. It means happening, taking place, or coming about.
The base verb is:
occur → occurring
For example:
Changes are occurring rapidly.
Here, occurring means that the changes are happening rapidly.
The word can describe events, situations, problems, changes, or anything else that is taking place.
Common synonyms for occurring
Depending on the context, synonyms include:
- happening
- taking place
- arising
- developing
- unfolding
- coming about
- transpiring
However, these words are not always interchangeable in every sentence. Occurring is often the most neutral and direct choice when you simply want to say that something is happening.
Why Is “Occurring” Spelled With Two R’s?
The spelling becomes easier to understand when you look at the base word:
occur
The word occur ends in a consonant, r. When you add the suffix -ing, the final r is doubled:
occur + ing = occurring
This gives us:
O C C U R R I N G
Notice that there are two r’s immediately before -ing.
The incorrect form occuring drops one of those r’s.
A simple way to remember it
Think:
occur → RR → occurring
Or remember the phrase:
It occurs with two R’s, so it is occurring with two R’s.
This small spelling trick can help prevent the mistake when writing quickly.
Occurring vs Occuring: The Main Difference
The biggest difference is simple: occurring is a correctly spelled English word, while occuring is not.
Occurring is used when something is happening or taking place.
For example:
- An accident is occurring on the highway.
- A change is occurring in the market.
- Several problems are occurring simultaneously.
On the other hand, occuring is simply a spelling error. If you see it in a document, it should normally be corrected to occurring.
Examples of “Occurring” in Sentences
Seeing the word in context makes the spelling and meaning easier to remember.
Everyday examples
- What is occurring outside?
- Strange noises were occurring throughout the night.
- The same mistake is occurring again.
- Several changes are occurring at work.
Academic examples
- Researchers are examining the changes occurring in the atmosphere.
- The study explains why certain reactions are occurring.
- Scientists observed several unusual behaviors occurring during the experiment.
Business examples
- A technical problem is occurring on the website.
- Delays are occurring because of bad weather.
- Several changes are occurring within the organization.
Formal writing examples
- The event is occurring at a particularly important time.
- Significant changes are occurring across the industry.
- The issue appears to be occurring more frequently.
Common Mistakes With “Occurring”
Because occurring contains several letters in a row, it is easy to misspell.
Mistake 1: Writing “occuring”
❌ The problem is occuring again.
✅ The problem is occurring again.
The incorrect version has only one r before -ing.
Mistake 2: Forgetting the second “c”
The base word is occur, not ocur.
❌ ocuring
❌ ocuring
✅ occurring
The correct spelling contains two c’s and two r’s:
occurring
Mistake 3: Confusing “occurred” and “occurring”
These words are related but use different endings:
- occurred = happened in the past
- occurring = happening or taking place
Examples:
The accident occurred yesterday.
The accident is occurring right now.
Both are correctly spelled, but they serve different grammatical purposes.
Occur, Occurs, Occurred, and Occurring
Understanding the complete word family can make the spelling easier.
| Form | Example |
| occur | Problems can occur unexpectedly. |
| occurs | This problem often occurs in winter. |
| occurred | The accident occurred yesterday. |
| occurring | The accident is occurring now. |
Notice the spelling pattern:
occur → occurs → occurred → occurring
The double r becomes especially noticeable in occurred and occurring.
Why Is “Occuring” Such a Common Misspelling?
The mistake is understandable because English spelling does not always make consonant doubling obvious.
When people add -ing, they may simply attach the ending to the word:
occur + ing → occuring
But English spelling requires the final consonant to be doubled in this case:
occur + ing → occurring
This is why occuring can look familiar even though it is incorrect.
Another reason is pronunciation. When we say occurring, the double r is not pronounced as two separate sounds. Because spelling and pronunciation do not perfectly match, writers may accidentally leave one r out.
American vs British English: Is There a Difference?
No. There is no American vs. British spelling difference between occurring and occuring.
Both American English and British English use:
occurring
For example:
- American English: The problem is occurring frequently.
- British English: The problem is occurring frequently.
The spelling remains the same in both varieties of English.
This makes the answer straightforward: regardless of whether you are writing for an American or British audience, choose occurring.
How to Remember the Correct Spelling
A useful memory trick is to start with the base word:
OCCUR
Now add -ING:
OCCUR + ING
Because the final r is doubled, the result is:
OCCURRING
You can also break the spelling into parts:
occ + urr + ing
The most important part to remember is:
“Occurring has two R’s.”
If you remember that phrase, you are much less likely to write occuring by accident.
Is “Occuring” Ever Correct?
No. In standard modern English, occuring is considered a misspelling.
If you encounter occuring in an article, message, essay, or other text, the intended word is almost certainly occurring.
Use:
✅ occurring
Avoid:
❌ occuring
This applies to formal and informal writing alike.
