The word comes from the verb:
occur
When forming the past tense, English follows a common spelling rule.
If a verb ends with:

- Followed by one consonant
the final consonant is often doubled before adding -ed.
Examples:
| Base Word | Past Tense |
| Stop | Stopped |
| Refer | Referred |
| Admit | Admitted |
| Occur | Occurred |
Because occur ends with r, we double the r:
✅ Occur → Occurred
❌ Occur → Occured
