If you’ve ever paused mid-sentence wondering whether to write occurring or occuring, you’re not alone. This is one of those tricky spelling differences that can slip past even confident writers.
A single missing letter can make your writing look less polished especially in emails, essays, blog posts, or professional documents.
In this guide, we’ll break down occurring vs occuring in the simplest way possible.
You’ll learn the correct spelling, why the confusion happens, how to remember the rule, and how to avoid common mistakes. Let’s clear it up once and for all.
Quick Answer:
- ✅ Occurring is the correct spelling.
- ❌ Occuring is incorrect and considered a spelling mistake.
The correct form has double “r” because of English spelling rules when adding “-ing” to certain verbs.
What Does “Occurring” Mean?
Occurring is the present participle of the verb occur. It means:
- Happening
- Taking place
- Existing or found somewhere
- Arising or coming to mind
Examples in Sentences
- The meeting is occurring right now.
- A strange noise is occurring in the engine.
- This issue is occurring more frequently.
- The error is occurring during login.
As you can see, “occurring” is commonly used in both everyday and formal writing. It appears often in business reports, academic texts, technical documentation, and news articles.
Why Is “Occuring” Incorrect?
The confusion between occurring vs occuring comes from misunderstanding a basic English spelling rule.
The base verb is occur (with two “r” letters). When we add -ing, we must double the final consonant because:
- The word ends in a consonant (r).
- The consonant is preceded by a single vowel (u).
- The stress falls on the final syllable: oc-CUR.
So:
- occur → occurring ✅
- occur → occuring ❌
Dropping one “r” breaks the spelling rule and results in a misspelling.
The Spelling Rule Explained Simply
Here’s the general rule for verbs like occur:
When a verb:
- Has one syllable OR
- Has stress on the final syllable
- Ends in consonant-vowel-consonant (CVC)
👉 Double the final consonant before adding -ing or -ed.
More Examples
- refer → referring
- begin → beginning
- admit → admitting
- occur → occurring
This pattern helps explain why “occurring” must keep both “r” letters.
Occurring vs Occuring: Side-by-Side Comparison
| Feature | Occurring | Occuring |
| Correct spelling | ✅ Yes | ❌ No |
| Dictionary recognized | ✅ Yes | ❌ No |
| Used in formal writing | ✅ Yes | ❌ No |
| Follows spelling rule | ✅ Yes | ❌ No |
| Looks professional | ✅ Yes | ❌ Risky |
If you’re writing professionally, academically, or even posting online, using the correct spelling matters for credibility.
Common Mistakes People Make
Let’s look at why writers often type “occuring” instead of “occurring.”
1. Forgetting the Double “R”
Since the pronunciation doesn’t strongly emphasize both “r” sounds, it’s easy to forget one.
2. Typing Too Quickly
Fast typing often leads to dropping repeated letters.
3. Confusion With Similar Words
Some English words don’t double the consonant when adding -ing. For example:
- open → opening
- listen → listening
This inconsistency makes English spelling tricky.
4. Autocorrect Over-Reliance
Sometimes autocorrect misses the mistake, especially in informal writing platforms.
American vs British English: Is There a Difference?
Good news there is no difference between American and British English for this word.
- 🇺🇸 American English: occurring
- 🇬🇧 British English: occurring
Unlike words such as “color/colour” or “traveling/travelling,” the spelling of occurring remains the same in both forms of English.
So no matter where you’re writing, the United States, United Kingdom, Canada, Australia, or anywhere else occurring is always correct.
Real-Life Usage Contexts
To fully understand occurring vs occuring, let’s see where “occurring” commonly appears.
In Business Writing
- An error is occurring in the system.
- Delays are occurring due to weather conditions.
In Academic Writing
- The phenomenon is occurring more frequently in urban areas.
- These changes are occurring at a rapid pace.
In Everyday Communication

Because it appears in technical, professional, and casual contexts, mastering this spelling improves overall writing clarity.
Easy Memory Trick to Remember
Here’s a simple trick:
Think of it as already having two “r” letters.
When something keeps happening, it still occur + r + ing.
Or remember this phrase:
“It’s reoccurring with two R’s.”
The repetition in the word matches the repeated letter.
Related Words You Should Spell Correctly
Understanding similar word forms strengthens your spelling accuracy:
- Occurred
- Occurrence
- Reoccurring
- Reoccurred
All of these maintain the double “r” because the root word is occur.
Why Correct Spelling Matters (E-E-A-T Perspective)
From a writing credibility standpoint, correct spelling impacts:
- Experience – Shows familiarity with standard English rules
- Expertise – Demonstrates language competence
- Authoritativeness – Builds reader trust
- Trustworthiness – Reduces doubt in professional content
Search engines also favor high-quality, error-free content. Even small spelling mistakes like “occuring” can reduce perceived authority.
