If you are confused about occurring vs occuring, the correct spelling is occurring. Occuring is a common misspelling. The word occurring means happening, taking place, or existing at a particular time. For example, “The problem is occurring again” is correct. The spelling contains two r’s: o-c-c-u-r-r-i-n-g.
This word often causes confusion because English spelling rules can become tricky when a verb ends in a stressed syllable and takes the -ing ending. The base verb is occur, and when we add -ing, the final r is doubled: occur → occurring. Therefore, remembering the correct spelling is important for students, ESL learners, writers, and anyone who wants to write clearly. Moreover, understanding the word’s meaning and related forms—such as occur, occurred, occurrence, and recurring—can help you use it accurately in different sentences and contexts.
Quick Answer
Occurring is the correct spelling, while occuring is incorrect. Occurring is the present participle of occur, meaning “happening” or “taking place.” Remember that occur ends with one r, but adding -ing doubles the final consonant: occur → occurring.
Why Do People Confuse It?
People often confuse occurring and occuring because the base word occur contains two c’s but only one r.
When -ing is added, the final r is doubled:
occur → occurring
As a result, the correct spelling contains:
cc + u + rr + ing
Many people remember the first part of the word correctly but forget to double the final r.
For example:
❌ occuring
✅ occurring
Therefore, focusing on the final part of the word can make the spelling easier to remember.
What Does the First Word Mean: Occurring?
Definition of Occurring
Occurring means happening, taking place, or existing at a particular time or in a particular situation.
For example:
“The accident was occurring near the highway.”
More naturally, you might say:
“A serious problem is occurring in the system.”
The word can describe events, problems, changes, situations, or natural processes.
Occurring in Everyday English
You may see occurring in sentences about things that are happening now or repeatedly.
For example:
“The same error is occurring every day.”
Here, occurring means that the error is happening repeatedly.
You can also use it in formal writing:
“Several changes are occurring in the industry.”
Therefore, occurring works in both everyday and formal contexts.
What Does the Second Word Mean: Occuring?
Is Occuring Correct?
Occuring is an incorrect spelling of occurring.
For example:
❌ “The problem is occuring again.”
✅ “The problem is occurring again.”
The mistake happens because writers sometimes forget that the final r in occur doubles before -ing.
Why Is Occuring Incorrect?
The base verb is:
occur
When -ing is added, the final consonant is doubled:
occur + ing → occurring
Therefore:
Occurring ✅
Occuring ❌

When Should You Use Each?
When to Use Occurring
Use occurring when you want to describe something that is happening or taking place.
For example:
“The changes are occurring gradually.”
It can describe:
- events
- problems
- changes
- reactions
- incidents
- trends
- natural processes
When to Use Occuring
Avoid occuring in standard English writing.
If you mean “happening,” use:
occurring
For example:
❌ “Several errors are occuring.”
✅ “Several errors are occurring.”
When to Use Occur
Use occur as the base or present-tense form of the verb.
For example:
“Problems can occur at any time.”
You can also use it with singular third-person subjects:
“An error occurs when the system fails.”
When to Use Occurred
Use occurred when something happened in the past.
For example:
“The accident occurred last night.”
Notice that occurred also has a doubled r:
occur → occurred

Common Mistakes
Mistake 1: Writing Occuring
The most common mistake is leaving out one r.
Incorrect:
“The error is occuring frequently.”
Correct:
“The error is occurring frequently.”
Mistake 2: Forgetting the Double R
The correct spelling is:
O-C-C-U-R-R-I-N-G
There are two r’s immediately before -ing.
Mistake 3: Confusing Occurring With Occurred
Both words contain double r, but they have different grammatical forms.
Occurring:
“The problem is occurring now.”
Occurred:
“The problem occurred yesterday.”
Therefore, choose the form based on the time and grammatical structure of the sentence.
Mistake 4: Confusing Occurring With Recurring
Occurring simply means happening or taking place.
Recurring means happening repeatedly.
For example:
“The problem is occurring now.”
“The problem is recurring every month.”
Thus, recurring gives the additional idea of repetition.
What Is an Easy Memory Trick?
Remember “Occur Has Double R When Growing”
A useful way to remember the spelling is:
OCCUR + ING = OCCURRING
Think of the final R as getting a partner before -ing is added.
So:
occur → occurring
not:
occur → occuring
You can also break the spelling into parts:
OCC + URR + ING
The important section to remember is:
URRING
Therefore:
Occurring = double R
