Occurred or Occured: Which Is Correct?
Updated · Which One Is Correct editorial team
Quick answer: The correct spelling is occurred, with two r’s. This verb means to happen or take place. Many people drop the second r by mistake, thinking it follows standard singular patterns. Always use the doubled consonant when referring to past events or specific instances that have already happened.
The Short Answer
"Occurred" is correct.
Confusion arises because most one-syllable verbs simply add -ed to form the past tense. Since occur ends in a single vowel followed by a single consonant, English rules require doubling the final letter before adding the suffix.
Side-by-Side Comparison
| Form | Status | Use it when |
|---|---|---|
| Occurred | Correct | Describing a past event or situation |
| Occured | Incorrect | Never use this misspelling |
| Occur | Correct | Speaking in present tense |
| Occurrence | Correct | Referring to the event as a noun |
