If you’ve ever paused while typing “occurring” or “occuring,” you’re not alone. This is a very common spelling confusion even for fluent English writers because of the tricky double letters.
Let’s clear it up so you can write it correctly every time.
Quick Answer
“Occurring” is the correct spelling.
“Occuring” is incorrect and should not be used.
✔ Correct: The issue is occurring frequently.
❌ Incorrect: The issue is occuring frequently.
What Does “Occurring” Mean?
“Occurring” is the present participle (or -ing form) of the verb “occur.” It means:
- Happening
- Taking place
- Coming into existence
Examples of “Occurring”
- The problem is occurring more often than before.
- A meeting is occurring right now.
- Changes are occurring rapidly in technology.
- The event is occurring next week.
Why Is It “Occurring” (Double “r”)?
This is where most people get confused.
The verb “occur” ends with a stressed syllable and a consonant (r). When adding “-ing,” you double the final consonant before adding the suffix.
Rule:
👉 If a verb ends in:
- vowel + consonant
- and the last syllable is stressed
➡ You double the consonant before adding “-ing”
So:
- Occur → Occurring ✔
- Refer → Referring ✔
- Begin → Beginning ✔
Why “Occuring” Is Wrong
“Occuring” drops one “r,” which breaks the spelling rule. It’s a common typo caused by:
- Forgetting the doubling rule
- Typing quickly
- Mispronunciation
Using “occuring” in formal writing can reduce credibility and readability.
