Have you ever wondered if to write occurred or occured? These words look almost the same, but only one is correct in standard English.
Occurred is the correct spelling. Occured is a spelling mistake. The word occurred is the past tense and past participle of occur. It means that something happened or took place.
The main thing to remember is that occurred has two C’s and two R’s.
Quick Answer: Occurred or Occured?
Occurred is correct, while occured is incorrect.
- ✅ Occurred: The event occurred yesterday.
- ❌ Occured: The event occured yesterday.
The correct spelling contains two C’s and two R’s: O-C-C-U-R-R-E-D.
Use occurred in schoolwork, emails, reports, articles, and other forms of writing. The spelling is the same in American and British English.
What Does Occurred Mean?
Occurred is the past tense and past participle of the verb occur. It means that something happened, took place, or came about.
Writers often use this word when talking about events, problems, changes, accidents, and other situations.
For example, a writer may say that an error occurred during a computer update. This means the error happened during that process.
The word can also describe an idea that came into someone’s mind. The phrase “it occurred to me” means that someone suddenly thought of something.
Why Is Occurred the Correct Spelling?
The correct spelling comes from the base verb occur.
When you change occur to its past tense, you double the final r before adding -ed.
- Base form: occur
- Past tense: occurred
- Past participle: occurred
- Present participle: occurring
The spelling rule gives us occurred, not occured. The same doubled R appears in occurring. The Government of Canada’s English writing guidance also confirms the double-R spelling in these forms.
Why Is Occured Incorrect?
Occured is incorrect because it has only one R after the U. It leaves out a letter from the standard spelling.
This mistake is easy to make because the correct word already contains two C’s, and the extra R can be easy to overlook when typing quickly.
Remember that the past tense does not remove or skip the second R. You must write occurred every time you use this past form.
