Have you ever written “occuring” and felt unsure if it was right? You are not alone. Many students lose marks or look unprofessional in emails because of this small spelling mistake.
The confusion is simple: one extra letter changes everything. In this guide, you will clearly understand occurring vs occuring, learn the correct spelling, and master the rule so you never make this mistake again.
Quick Answer
- ✅ Correct spelling: occurring
- ❌ Incorrect spelling: occuring
- The correct form follows a double consonant spelling rule
- Use occurring when something is happening now
Simple Background
To understand occurring spelling, start with the base word: occur.
“Occur” means to happen or to take place.
Examples:
- The event will occur tomorrow.
- A mistake occurred yesterday.
When we add ing, many learners get confused between occuring or occurring.
Why “Occurring” Has Two R’s (Simple Rule)
Many learners ask: why is occurring spelled with two r?
Here is the easy rule:
If a word ends with:
- a short vowel + one consonant
You double the last letter before adding “ ing.”
So:
- occur → occurring ✅
This is part of basic English grammar rules and helps avoid common spelling mistakes in English.
More Examples of This Rule
- begin → beginning
- admit → admitting
- refer → referring
These examples help you see the pattern clearly.
The Real Difference (Occurring vs Occuring)
There is no real choice here:
- Occurring → correct spelling
- Occuring → spelling mistake
“Occuring” breaks the rule and is not accepted in correct English.

Occur vs Occurring (Easy Understanding)
Many learners also mix occur vs occurring.
- Occur → base form
- Occurring → action happening now
Examples:
- Problems occur often.
- Problems are occurring right now.
Occurring vs Occurred Difference
Another confusion is occurring vs occurred difference.
- Occurred → past (already happened)
- Occurring → present (happening now)
Examples:
- The error occurred yesterday.
- The error is occurring now.
When to Use “Occurring”
Use occurring when something is happening in the present or over time.
Examples of occurring in sentences:
- A problem is occurring in the system.
- Changes are occurring in the environment.
- Something strange is occurring here.
- Growth is occurring quickly.
Why “Occuring” Is Always Wrong
“Occuring” is missing one “r.”
It does not follow the spelling rules for occurring, so it is incorrect in:
- Exams
- Emails
- Assignments
- Job applications
This is one of the most common ESL spelling mistakes.
Real Life Examples
In Emails
❌ An error is occuring in the system.
✅ An error is occurring in the system.

Similar Words That Follow This Rule
Learning similar words helps you master the pattern:
- stop → stopping
- plan → planning
- run → running
- sit → sitting
These follow the same double consonant spelling rule.
Important Exception (So You Don’t Get Confused)
Not all words double the last letter.
Example:
- open → opening (NOT openning)
Why?
Because “open” does not have the same stress pattern.
This helps you understand deeper English grammar basics.
