When something happens more than once, should you call it recurring or reoccurring? The two words are close enough to confuse even careful writers, especially in phrases such as recurring problem, reoccurring issue, recurring payment, and reoccurring error.
The good news is that both recurring and reoccurring are legitimate English words. The difference is mainly one of emphasis. Recurring is the established choice when something happens repeatedly or forms a pattern.
Reoccurring comes from reoccur and puts more emphasis on something happening again. Oxford lists reoccur as meaning “to happen again or a number of times,” while Cambridge defines recurring as something happening many times or again.
So the choice is not simply “one is correct and the other is wrong.” In many sentences they overlap, but recurring is usually the more natural and established choice when you mean repeated or ongoing occurrence.
Quick Answer
Recurring usually describes something that happens repeatedly, often as a continuing pattern or at regular intervals: a recurring problem, a recurring payment, a recurring dream.
Reoccurring means happening again. It can be useful when you want to emphasize that something has happened another time, without necessarily suggesting a regular pattern.
Both words are correct. If you are unsure, recurring is generally the safer choice for established repeated patterns, routines, themes, payments, and ongoing problems.

Cambridge lists recurring as an adjective meaning “happening many times, or happening again,” and Oxford gives recurring as the -ing form of recur. Oxford separately recognizes reoccurring as the -ing form of reoccur.
Quick tip: If you are describing something that has become a pattern, recurring is usually the better word. If you specifically want to stress that something has happened again, reoccurring can make that emphasis clearer.
What Does “Recurring” Mean?
Recurring means happening again and again, or appearing repeatedly over time.
It comes from the verb recur. Oxford traces recur to Middle English and ultimately to Latin recurrere, meaning “to run back,” from re- (“again, back”) and currere (“run”).
Cambridge defines recurring as something that happens many times or happens again. It also gives a business-specific meaning for things such as recurring revenue, recurring costs, and recurring expenses: things that happen or are paid regularly rather than only once.
Examples of “Recurring”
- a recurring problem
- a recurring payment
- a recurring dream
- a recurring theme
- a recurring mistake
- a recurring meeting
- a recurring expense
- a recurring pattern
- a recurring headache
- a recurring event
Consider:
We have a recurring problem with the server.
The sentence suggests that the problem has appeared repeatedly and has become a recognizable pattern.
Likewise:
The company has several recurring expenses each month.
Here, the repetition is expected and regular. Cambridge specifically uses recurring in financial contexts for revenues, costs, and expenses that occur regularly.
Recurring in Everyday English
Recurring is natural when talking about things that return repeatedly:
She has a recurring dream about being lost.
The same argument became a recurring issue in their meetings.
Rain is a recurring feature of the region during this season.
His name is a recurring theme throughout the novel.
Cambridge’s examples similarly show recurring with words such as nightmare, theme, bouts, feature, and pattern.
Recurring in Professional and Business English
This is where recurring is particularly common.
You will often see:
- recurring revenue
- recurring costs
- recurring expenses
- recurring subscription
- recurring payment
- recurring meeting
- recurring task
- recurring customer
- recurring charge
For example:
The software company earns most of its revenue from recurring subscriptions.
Please check whether the recurring payment has been processed.
We need to reduce our monthly recurring expenses.
This is not merely a grammar preference. Recurring has become a well-established business collocation. Cambridge’s Business English entry specifically uses it for regular financial activity.
What Does “Reoccurring” Mean?
Reoccurring is the present participle of reoccur.
The verb reoccur means to occur again or a number of times. Oxford lists reoccur as an intransitive verb and gives reoccurring as its -ing form.
The important point is that reoccurring is not a misspelling of recurring.
For example:
We took steps to prevent the problem from reoccurring.
That sentence is grammatically valid.
The word can be particularly useful when the writer wants to focus on another occurrence of an event rather than describing a stable or predictable pattern.
Reoccurring Does Not Mean “Wrong”
A common misconception is:
❌ Reoccurring isn’t a real word.
That is incorrect.
Oxford has a separate entry for reoccur, including its -ing form reoccurring.
So:
The error is reoccurring.
is not automatically grammatically wrong.
However, the fact that a word is valid does not mean it is always the most natural choice.
When “Reoccurring” Makes Sense
Suppose a software error occurred once last month and has now appeared again.
You might write:
We need to investigate why the error is reoccurring.
The focus is on the error occurring again.
Compare that with:
We have a recurring error in the payment system.
This version sounds more like the error has become a repeated pattern.
That distinction is useful, although real-world English does not always maintain a strict boundary between the two words. Dictionary.com similarly describes reoccur as focusing on something happening again without necessarily specifying how often or regularly, while recur is typically associated with repeated or regular occurrence.
The Main Difference Between Recurring and Reoccurring
The simplest way to understand the difference is to think about pattern versus another occurrence.
Recurring = repeated pattern
Use recurring when something keeps appearing, happening, or returning.
We have a recurring problem with late deliveries.
The problem is not simply happening one additional time. It has become a repeated issue.
Reoccurring = happening again
Use reoccurring when the important idea is that something has occurred again.
We need to stop the error from reoccurring.
The emphasis is on preventing another occurrence.
But the distinction is not absolute
This is important.
English dictionaries do not establish a rigid rule saying:
recurring = regular
reoccurring = exactly twice
That would be too simplistic.
Oxford defines reoccur broadly as “to happen again or a number of times,” while Cambridge defines recur as “to happen many times or to happen again.” Their meanings therefore overlap.
The distinction is best treated as a usage tendency, not an unbreakable grammar rule.
Are Recurring and Reoccurring Both Correct?
Yes.
Both are legitimate forms.
- recurring → from recur
- reoccurring → from reoccur
Oxford recognizes both underlying verbs.
The more useful question is not:
Which one is grammatically correct?
It is:
Which one communicates my intended meaning most naturally?
For most situations involving an established repeated pattern, recurring is the more idiomatic choice.
For a specific event that has happened again, reoccurring may be appropriate when the writer wants to emphasize that renewed occurrence.
Recurring vs Reoccurring in Different Contexts
Recurring Problems
Use recurring when a problem keeps returning:
The company has a recurring problem with its website.
This sounds natural because the problem has become a pattern.
Reoccurring Problems
You can also say:
The problem is reoccurring despite the software update.
Here, the writer emphasizes that the problem is happening again.
Both are possible, but they frame the situation slightly differently.
Recurring Payments
Recurring payment is the standard phrase for a payment that happens repeatedly according to an arrangement or schedule.
Your recurring payment will be processed on the first of each month.
This is a particularly strong example of why recurring is preferable when regularity is central.
Reoccurring Payments
Reoccurring payment is understandable, but it is usually not the natural business term when you mean an automatic or scheduled payment.
If you are describing a subscription, direct debit, membership fee, or automatic monthly charge, recurring payment is the conventional choice.
Recurring Events
The conference is a recurring event held every spring.
The word fits because the event belongs to a repeated pattern.
Reoccurring Events
The unexpected outage is reoccurring after each update.
Here, reoccurring can emphasize that the outage happens again, especially if the timing is not deliberately scheduled.
Recurring Themes
Freedom is a recurring theme in the author’s novels.
This is highly natural English. Cambridge’s dictionary and corpus material contain numerous examples of recurring theme and related combinations.
Reoccurring Themes
You may encounter:
A reoccurring theme in the story is isolation.
It is understandable, but recurring theme is generally the more established collocation.
Grammar: How to Use “Recurring”
Recurring comes from the verb recur.
Its forms include:
- recur
- recurs
- recurred
- recurring
Oxford lists these verb forms explicitly.
As an adjective
The most common role of recurring in this comparison is adjectival.
a recurring problem
a recurring dream
a recurring charge
Here, recurring modifies a noun.
As a present participle
It can also function as the present participle of recur:
The same problem is recurring.
Here, recurring forms part of the verb phrase is recurring.
Verb agreement
Because recur is an intransitive verb, it does not normally take a direct object.
Correct:
The problem recurred.
Correct:
The symptoms recurred.
Correct:
The issue keeps recurring.
Not:
❌ The manager recurred the problem.
Instead:
The manager reported the recurring problem.
Grammar: How to Use “Reoccurring”
The same basic grammatical principle applies.
The forms are:
- reoccur
- reoccurs
- reoccurred
- reoccurring
Oxford gives these forms in its entry for reoccur.
As an adjective
a reoccurring error
a reoccurring issue
a reoccurring incident
As a present participle
The error is reoccurring.
The problem keeps reoccurring.
After “from”
One common structure is:
prevent something from reoccurring
For example:
We changed the system to prevent the error from reoccurring.
Here, reoccurring is the -ing form following the preposition from.
Pronunciation: Recurring vs Reoccurring
The pronunciation helps explain why the two words sound different.
Recurring
UK: /rɪˈkɜːrɪŋ/
US: /rɪˈkɝːɪŋ/
Roughly:
ri-KUR-ing
Cambridge gives these UK and US pronunciations for recurring.
Reoccurring
UK: /ˌriːəˈkɜːrɪŋ/
US: /ˌriːəˈkɝːɪŋ/
Roughly:
ree-uh-KUR-ing
Oxford gives the pronunciation of reoccur and its -ing form.
Easy pronunciation tip
Think:
- recurring → re-CUR-ring
- reoccurring → re-oc-CUR-ring
The second word contains the recognizable re + occur structure.

Common Mistakes With Recurring and Reoccurring
Mistake 1: Assuming “reoccurring” is always wrong
Wrong assumption:
“Reoccurring isn’t a real English word.”
Why it is wrong:
Oxford recognizes reoccur and its form reoccurring.
Better understanding:
Both recurring and reoccurring are legitimate words.
Mistake 2: Treating them as completely identical
Although they overlap, they can emphasize different ideas.
Compare:
We have a recurring problem.
with:
The problem is reoccurring.
The first naturally suggests an established pattern. The second focuses more directly on the problem happening again.
Mistake 3: Using “reoccurring” for a scheduled payment
Less natural:
I canceled my reoccurring payment.
More natural:
I canceled my recurring payment.
A scheduled payment is inherently repetitive, making recurring the conventional choice.
Mistake 4: Misspelling “recurring”
A common spelling problem is adding too many letters.
Correct:
recurring
Not:
❌ reccurring
The word comes from recur, whose spelling changes to recurring rather than reccurring.
Oxford lists the -ing form as recurring.
Mistake 5: Confusing “reoccurring” with “occurring”
These words are related but not interchangeable.
- occurring = happening
- reoccurring = happening again
- recurring = happening repeatedly or again
For example:
The problem is occurring.
means the problem is happening.
The problem is reoccurring.
means the problem is happening again.
The problem is recurring.
suggests the problem keeps returning or has become a repeated pattern.
Recurring vs Reoccurring in Formal Writing
For formal writing, the choice should depend on the meaning you want to communicate.
If you are discussing a pattern, regular event, repeated problem, recurring expense, recurring theme, or established trend, recurring is usually the cleanest choice.
Examples:
recurring expenses
recurring revenue
recurring themes
recurring patterns
recurring meetings
recurring problems
If you specifically need to emphasize another occurrence, reoccurring can be useful:
measures designed to prevent the error from reoccurring
That said, many editors would simply use recurring or rewrite the sentence with happening again if reoccurring feels unnecessarily cumbersome.
Is Recurring More Formal Than Reoccurring?
Not exactly.
It would be misleading to say:
recurring = formal
reoccurring = informal
Both can appear in formal English.
The more useful distinction is established usage and semantic emphasis.
Recurring has a very broad and established range of uses, including business, academic, literary, and everyday contexts. Cambridge, for example, documents recurring in general English as well as Business English.
Reoccurring is also legitimate, but it is less likely to be the conventional choice in fixed expressions such as recurring revenue or recurring payment.
US English vs UK English
There is no major US-versus-UK rule that makes one word American and the other British.
Both recurring and reoccurring occur in both varieties.
The more important issue is normal English usage rather than regional grammar.
Pronunciation differs slightly between American and British English, particularly in the vowel represented by the stressed syllable. Cambridge provides both UK and US pronunciations for recurring, while Oxford provides UK and American pronunciation information for reoccur.
So you do not need to switch from recurring to reoccurring simply because you are writing for an American or British audience.
Recurring vs Reoccurring vs Recurrent
There is a third word worth knowing: recurrent.
Recurrent is an adjective meaning something that happens again many times. Cambridge gives examples such as recurrent episodes, recurrent themes, and recurrent expenditure.
Compare:
- recurring problem
- recurrent problem
- reoccurring problem
All can be understandable, but their style and emphasis differ.
Recurring
Usually the most straightforward everyday choice.
a recurring problem
Recurrent
Often sounds somewhat more formal, technical, or established in specialized vocabulary.
recurrent episodes
recurrent symptoms
recurrent themes
Reoccurring
Emphasizes occurrence again and is less common in some fixed expressions.
prevent the problem from reoccurring
Important distinction
Do not assume that recurrent and recurring have completely different meanings. Cambridge explicitly lists recurring as a synonym-related form and defines recurrent as happening again many times.
Recurring, Reoccurring, and “Repeated”
Another useful comparison is repeated.
Repeated simply means something happened more than once.
a repeated mistake
Recurring often suggests that something returns or forms a pattern.
a recurring mistake
Reoccurring emphasizes another occurrence.
the mistake is reoccurring
You can often replace recurring with repeated, but the tone and nuance may change.
a recurring theme
sounds more natural than:
a repeated theme
Similarly:
recurring revenue
is a specialized business expression, whereas repeated revenue does not communicate the same established concept.
Memory Tricks
Here are a few easy ways to remember the distinction.
Trick 1: Pattern = Recurring
If something is part of a pattern, think:
Recurring
Examples:
- recurring payment
- recurring meeting
- recurring theme
- recurring problem
Trick 2: Again = Reoccurring
If you want to emphasize:
“It happened, and now it has happened again.”
think:
Reoccurring
Trick 3: Think of “recur”
Recur → recurring
The word has a long-established connection with repetition and return.
Trick 4: Don’t treat “reoccurring” as an error
Remember:
Reoccur is a real verb.
Therefore:
reoccurring is a real word.
Oxford confirms the verb and its -ing form.
Memory shortcut:
Recurring = repeated pattern.
Reoccurring = occurring again.
Frequently Asked Questions
Is “reoccurring” a correct word?
Yes. Reoccurring is a correct English word. It is the present participle of reoccur, a verb recognized by dictionaries such as Oxford.
Is recurring or reoccurring correct?
Both are correct. Recurring is generally preferred for something that repeatedly happens or forms a pattern. Reoccurring can emphasize that something happens again.
Is there a real difference between recurring and reoccurring?
There can be a difference in emphasis. Recurring commonly suggests repeated occurrence or a pattern, while reoccurring focuses more directly on something occurring again. However, the meanings overlap, so the distinction is not absolute.
Is “recurring problem” or “reoccurring problem” better?
Both are possible, but recurring problem is generally the more natural choice when you mean a problem that repeatedly returns.
We have a recurring problem with the server.
Is it “recurring payment” or “reoccurring payment”?
Recurring payment is the standard choice for an automatic or scheduled payment. Cambridge specifically uses recurring for payments, revenues, costs, and expenses that happen regularly.
Is recurring more common than reoccurring?
In established expressions and general usage, recurring is generally the more conventional choice. However, reoccurring is a legitimate word and should not automatically be treated as an error. Dictionary.com describes a usage distinction between the two, while Oxford recognizes both underlying verbs.
Can recurring and reoccurring be used interchangeably?
Sometimes. Because both words can describe something happening again, they overlap in many sentences. But they are not always equally natural. Choose recurring for established repeated patterns and conventional phrases; choose reoccurring when emphasizing another occurrence is useful.
Which should I use in professional writing?
Use recurring when you mean something that happens repeatedly, especially with terms such as recurring costs, recurring revenue, recurring payments, recurring meetings, and recurring issues. Use reoccurring when the specific meaning of “occurring again” matters.
Final Verdict
The answer is not that one word is correct and the other is incorrect.
Recurring and reoccurring are both legitimate English words, but they have different usage tendencies.
Use recurring when something happens repeatedly, returns as a pattern, or occurs on a regular basis:
- recurring payment
- recurring expense
- recurring problem
- recurring theme
- recurring meeting
- recurring dream
- recurring pattern
Use reoccurring when you want to emphasize that something has occurred again, especially when regularity or a predictable pattern is not the main point:
- a reoccurring error
- a reoccurring issue
- prevent the problem from reoccurring
- the fault is reoccurring
Oxford recognizes recur and reoccur as separate verbs, while Cambridge defines recurring broadly as happening many times or again.
The safest rule
Use “recurring” for repeated patterns and established recurring expressions. Use “reoccurring” when you specifically want to emphasize something happening again.
If you are writing a sentence such as “This is a ___ problem,” recurring problem will usually be the most natural choice.
If your sentence is “We need to prevent the problem from ___,” reoccurring can be a natural choice when the emphasis is on preventing another occurrence.
So, when choosing between recurring vs reoccurring, don’t ask only, “Which word is correct?” Ask what your sentence is trying to emphasize: a repeated pattern or another occurrence. That small distinction will usually lead you to the right word.
