Occurred or Occured: Which Spelling Is Correct? 5+ Examples

If you are unsure whether to write occurred or occured, you are not alone. These two spellings look almost identical, but only one is correct in standard English.

The correct spelling is occurred with two c’s and two r’s. Occured is a common misspelling and should not be used in formal or everyday writing.

The word occurred is the past tense and past participle of occur. It usually means that something happened or took place. For example, “The accident occurred yesterday” means that the accident happened yesterday.

The easiest way to remember the spelling is to notice the two sets of double letters: CC and RR. Once you remember this pattern, choosing between occurred and occured becomes much easier.

Quick Answer: Occurred or Occured?

Occurred is the correct spelling. Occured is incorrect.

The correct spelling is:

O-C-C-U-R-R-E-D

It contains two c’s and two r’s.

For example:

• The meeting occurred on Monday.
• The problem occurred during the test.
• It occurred to me that I had forgotten my phone.

The spelling occured is missing one r.

What Does Occurred Mean?

Occurred is the past tense and past participle of the verb occur.

The most common meaning of occur is to happen or to take place. The word can also describe something that exists or is found in a particular place. The phrase “it occurred to me” has another common meaning: an idea or thought came into someone’s mind.

Examples:

• The accident occurred late at night.
• A technical problem occurred during the update.
• The event occurred several years ago.
• It suddenly occurred to me that I had left my keys at home.

Why Is Occurred Spelled With Two Rs?

The spelling comes from the base verb occur.

When the past-tense ending -ed is added, the final r is doubled:

occur → occurred

The same double-r pattern appears in the present participle:

occur → occurring

This is why the standard forms are occurred and occurring, not occured and occuring. The Canadian Language Portal specifically identifies occurred and occurring as forms with a double r.

A useful spelling pattern is:

occur + red = occurred

So don’t remove one of the r’s when adding -ed.

Occurred vs Occured: What’s the Difference?

The difference is simple: occurred is correct, while occured is a misspelling.

Spelling	Correct?	Explanation
occurred	✅ Yes	Standard English spelling
occured	❌ No	Missing one “r”
ocurred	❌ No	Missing one “c”
occurrred	❌ No	Contains an extra “r”

For standard English writing, always choose occurred.

For example:

❌ The accident occured yesterday.

✅ The accident occurred yesterday.

❌ The error ocurred during the test.

✅ The error occurred during the test.

Is Occured a Word?

No. Occured is not the standard spelling of the past tense of occur.

It is usually a spelling mistake caused by forgetting to double the final r. Because occur already ends with r, writers sometimes add -ed without making the necessary spelling change.

The correct pattern is:

occur → occurred

Not:

occur → occured

If you see occured in an email, essay, article, or document, it should normally be corrected to occurred.

How Do You Spell Occurred?

The correct spelling is:

O-C-C-U-R-R-E-D

You can break it into smaller parts:

OC + CURR + ED

Or simply remember:

Double C + Double R = occurred

The word begins with CC and contains RR before ED.

Seeing the word this way can make it easier to remember:

oCCuRRed

The visual pattern is especially useful when proofreading schoolwork, professional documents, or online content.

Examples of Occurred in a Sentence

Here are several natural examples of occurred:

1. The accident occurred early in the morning.
2. The meeting occurred as planned.
3. A power failure occurred during the storm.
4. The problem occurred after the software update.
5. Several changes occurred over the last year.
6. The incident occurred near the main entrance.
7. It never occurred to him that she might be upset.
8. The error occurred because of a technical issue.
9. The event occurred more than a decade ago.
10. A strange thought occurred to me while I was driving.

Notice that occurred refers to something that happened in the past.

Occur vs. Occurred

Occur is the base form of the verb, while occurred is its past tense and past participle.

Form	Use	Example
occur	Base form	Problems can occur.
occurs	Present tense	The error occurs frequently.
occurred	Past tense	The error occurred yesterday.
occurring	-ing form	The error is occurring again.

Examples:

Present:
Problems can occur without warning.

Past:
A problem occurred yesterday.

Present continuous:
The same problem is occurring again.

Understanding this word family can help prevent several common spelling mistakes.

Occurred vs. Occurring

Although these words look similar, they are used differently.

Occurred normally describes something that happened in the past.

The accident occurred yesterday.

Occurring describes something happening or taking place.

The accident is occurring right now.

The spelling also differs at the ending:

occur → occurred

occur → occurring

Both forms keep the double r.

Common Misspellings of Occurred

Because of its repeated letters, occurred is easy to misspell.

Some common incorrect forms include:

• occured ❌
• ocurred ❌
• occurd ❌
• occurrred ❌
• occuried ❌
• occurreded ❌

The standard form is simply:

occurred ✅

The most common mistake is occured, where one r has been left out.

Why Do People Write Occured?

The mistake usually happens because English spelling does not always work exactly as it sounds.

When people see occur, they may naturally think:

occur + ed = occured

But the correct spelling keeps the double r:

occur → occurred

The repeated letters can also make the word visually confusing. A writer may remember the double c but forget the second r.

That is why the simple memory rule “double C, double R” can be useful.

Easy Trick to Remember Occurred

Try this:

Occurred has two C’s and two R’s.

Look at the word:

oCCuRRed

You can think of the letters as two pairs:

CC + RR

Another useful approach is to start with the base word:

occur

Then add the ending while keeping the double r:

occur → occurred

If you remember the base spelling and the double-r pattern, you are much less likely to write occured.

Is Occurred Used in American and British English?

Yes. Occurred is the standard spelling in both American and British English.

There is no standard British spelling occured and American spelling occurred distinction. The correct form is occurred in both varieties.

This means you do not need to change the spelling depending on your audience.

Whether you are writing:

• an academic assignment,
• a business email,
• a website article,
• a report,
• a resume,
• or an everyday message,

occurred is the appropriate standard spelling.

When Should You Use Occurred?

Use occurred when you are describing something that happened or took place in the past.

For example:

The meeting occurred last Friday.

The issue occurred after the installation.

The accident occurred at approximately 8 p.m.

You can also use occurred to when describing an idea that came into someone’s mind:

It occurred to me that I had forgotten my wallet.

In this expression, the meaning is closer to “came to mind” rather than simply “happened.”

Occurred and “Happened”: Are They the Same?

In many sentences, occurred and happened have similar meanings.

For example:

The accident occurred yesterday.

and

The accident happened yesterday.

Both sentences communicate that the accident took place yesterday.

However, occurred often sounds more formal than happened. It is common in reports, academic writing, news writing, technical documents, and professional communication.

For casual conversation, happened may sound more natural.

When Should You Avoid Occurred?

Although occurred is correct, it is not always the most natural word.

In everyday conversation, people often use simpler words such as happened or took place.

For example:

Formal:

The incident occurred yesterday.

More conversational:

The incident happened yesterday.

The choice depends on context. Occurred is completely correct, but good writing also means choosing the word that fits the situation.

The Canadian Language Portal notes that occur can sometimes be replaced with more precise or natural alternatives such as “happen” or “take place.”
