Recur vs. Reoccur: What's the Difference?
Understand the subtle difference between recur and reoccur, including repeated patterns versus another occurrence, with examples, rules, a quiz, and FAQs.
Recur and reoccur can both mean happen again. Recur often suggests repetition, frequency, or a pattern, while reoccur simply states that something occurs again without necessarily implying a regular cycle. Recur is usually the more concise general choice.

How to use recur
Recur can describe something returning once, but it often carries a sense of repeated or periodic appearance. Its common related forms are recurred, recurring, and recurrence.
The billing error recurs near the end of each quarter.
How to use reoccur
Reoccur emphasizes another occurrence without adding a strong suggestion of frequency. It is valid, though recur is more established and often more economical.

Rules that make the choice easier
Use recur for a pattern
When an event returns repeatedly, periodically, or as a continuing theme, recur is the natural choice.
Use reoccur for a simple repeat
When the point is only that an event happened again, reoccur can make that limited meaning explicit.
Choose the more concise word when nuance is irrelevant
If the sentence does not depend on the subtle distinction, recur is shorter and familiar to more readers.
Common mistakes to avoid
- Do not claim that reoccur is automatically incorrect.
- Do not use reoccur merely to sound more formal.
- Spell the forms correctly: recurred and recurring double the final r.
