Reorder or re-order? If you have ever hesitated over this spelling, you are not alone. The confusion usually comes from the fact that re- can function as a prefix, while English also uses hyphens to prevent confusion in certain constructions. In modern American English, however, the standard spelling is usually reorder, without a hyphen.
The word reorder means to order something again, arrange something differently, or request another supply of something previously ordered. The hyphenated form, re-order, is much less common in contemporary American usage. Understanding when the hyphen is unnecessary, and when a writer might deliberately use one for clarity, can make your writing more consistent and professional.
Here’s the simple answer:
Reorder is generally the preferred spelling in American English. Re-order may appear occasionally, especially when a writer wants to make the meaning especially clear, but it is not normally necessary.
The Core Rule Explained Simply
The basic rule is straightforward: when re- is added to a word to mean “again” or “anew,” American English generally writes the resulting word as one word.
For example:
- reorder
- rewrite
- reorganize
- rebuild
- reconsider
- reconnect
- reopen
- rearrange
- reapply
- reassess
In each case, the prefix re- attaches directly to the base word. No space is needed, and no hyphen is normally required.
So, if you mean order again, write:
Please reorder the supplies.
Not:
Please re-order the supplies.
Let’s make this concrete.
Category 1: Reorder as One Word
Reorder is normally written as one word when re- means again or anew.
Examples:
- We need to reorder the books.
- Please reorder the paragraphs.
- The manager asked us to reorder the list.
- Customers can reorder their favorite products.
- She decided to reorder the information.
- We may need to reorder the materials.
The prefix creates a new word with a recognizable meaning. Because the meaning is clear, the hyphen usually adds nothing.
Category 2: Re-order as a Deliberate Clarity Device
Re-order can occasionally be found when a writer wants to emphasize the distinction between re- and the base word.
This can happen when a particular construction looks confusing, awkward, or potentially ambiguous. The hyphen visually separates the prefix from the root.
For example, a technical writer might use re-order to make the intended meaning immediately obvious in a specialized context.
However, this should not be treated as the normal spelling of the word. In standard American English, reorder is generally the safer default.

Deep Dive into Reorder
When Should You Use Reorder?
Use reorder when re- has its ordinary prefix meaning and creates a clear compound word.
The most common meaning involves ordering something again. A customer may reorder a product after using the first one. A company may reorder inventory when supplies run low. A restaurant may reorder ingredients from a supplier.
For example:
I need to reorder my usual coffee beans.
Here, reorder means the person is placing another order for something they previously purchased.
But reorder has another important meaning. It can mean to arrange things in a different sequence.
Consider this sentence:
The teacher asked students to reorder the sentences.
The students are not necessarily purchasing or requesting anything. They are changing the sequence of the sentences.
The same word works naturally in both contexts.
Look at this:
- Reorder the products = order the products again.
- Reorder the products on the page = arrange the products differently.
Context determines which meaning is intended.
Reorder Can Have Several Related Meanings
The word reorder is flexible because the basic concept of “order” can refer to either purchasing or arranging.
Consider these examples:
Purchase again:
We need to reorder printer paper.
Arrange differently:
The designer decided to reorder the images.
Change sequence:
Please reorder these steps.
Request another supply:
The pharmacy will reorder the item when inventory is low.
These meanings are connected by the idea of doing something with order again.
Quick Test for Reorder
Use this checklist before writing reorder:
- Does re- mean again?
- Does the resulting word have a clear meaning?
- Would removing the prefix leave a recognizable base word?
- Does the sentence sound natural when reorder is written as one word?
- Are you writing in standard contemporary American English?
If the answers are yes, reorder is almost certainly the form you want.
Here’s an easy test:
Can you replace “reorder” with “order again” or “arrange again”?
If yes, reorder is usually appropriate.
Examples of Correct Reorder Usage
Business
The company needs to reorder office supplies.
Retail
Customers can reorder products directly from their accounts.
Writing
The editor asked the author to reorder the sections.
Education
Students must reorder the events chronologically.
Technology
The application allows users to reorder items by dragging them.
Everyday conversation
I liked the meal so much that I decided to reorder it.
Each example uses reorder naturally without a hyphen.
Deep Dive into Re-order
Why Does Re-order Appear?
Although reorder is the standard modern form in most ordinary situations, you may still encounter re-order.
One reason is that writers sometimes use a hyphen to make the structure of a word more visible. Prefixes can occasionally create awkward combinations, especially when the resulting spelling could be misunderstood.
The hyphen can act as a visual signal:
re + order → re-order
Instead of allowing the reader to process the word as a single unit, the writer highlights the prefix.
However, a writer’s preference for visual clarity does not automatically make the hyphen necessary.
Re-order Is Not Usually Required
A common misconception is that every word beginning with re- needs a hyphen.
That is not how modern American English generally works.
Compare:
- rewrite, not re-write
- rebuild, not re-build
- reopen, not re-open
- reorganize, not re-organize
- reconsider, not re-consider
- reorder, not re-order
These words are normally closed compounds.
The hyphen should therefore not be added simply because the writer recognizes re- as a prefix.
When Could a Hyphen Help?
A hyphen may occasionally be useful if a particular construction could create genuine ambiguity or an awkward reading.
English spelling conventions are not purely mechanical. Writers sometimes use punctuation to help readers interpret unusual words or specialized terminology.
For example, a technical document may deliberately distinguish a newly coined or specialized term from an established word. In such cases, a hyphen can communicate the writer’s intended structure.
But there is an important distinction:
Possible does not mean preferred.
If you are writing a normal article, email, essay, report, product description, or webpage, reorder should generally be your first choice.
Patterns You Can Compare
The same general pattern appears with many other re- words:
- reenter
- reexamine
- reestablish
- reeducate
- reevaluate
- reengineer
- reedit
- reopen
- reorganize
- reorder
Some of these words can look visually crowded, but modern spelling often still treats them as single words.
This is why the presence of re- does not automatically create a hyphenation requirement.
The Meaning Shift, or Nuance
The meanings of reorder and re-order are usually not dramatically different.
In most ordinary contexts, both forms are intended to communicate the basic idea of ordering again or changing an existing order. The major difference is therefore not usually semantic. It is primarily a matter of spelling convention and editorial style.
This distinction matters.
If someone writes:
I need to re-order the documents.
A reader will almost certainly understand the sentence.
The hyphen does not normally transform the word into a completely different concept. Instead, it provides a visual separation between re- and order.
By contrast:
I need to reorder the documents.
This version follows the standard closed spelling used in contemporary American English.
So the practical difference is this:
Reorder = standard, natural, preferred in most American English writing.
Re-order = understandable and sometimes deliberately used, but generally less conventional.
Why the Confusion Persists
The confusion surrounding reorder or re-order comes from several sources.
First, English has no single universal rule that makes every prefix behave identically. Some prefixes combine naturally with words, while certain constructions may use hyphens for clarity.
Second, dictionaries, style guides, publishers, and individual organizations can have different editorial preferences. A reader may therefore encounter re-order in one publication and reorder in another.
Third, writers often assume that a prefix should be visually separated from the base word. That instinct makes sense because re- clearly carries meaning. Yet modern English spelling frequently combines prefixes directly with their base words.
There is also the influence of older writing habits.
Hyphenation conventions have changed over time. A form that appears in older documents does not necessarily represent the preferred spelling in current American English.
Digital writing creates another layer of confusion. Search results, product interfaces, internal documentation, and user-generated content can contain inconsistent spellings. Seeing re-order repeatedly can make it look more standard than it actually is.
Here’s the key takeaway:
Frequency in informal online writing does not automatically determine standard spelling.
Formal vs Casual Contexts
Formal Writing
In formal American English, consistency is especially important.
Use reorder in academic writing, professional reports, business documents, articles, instructions, and polished website content unless a specific style guide requires something else.
For example:
The editor decided to reorder the sections to improve the logical progression.
This looks clean and conventional.
Another example:
Customers may reorder previously purchased products through their accounts.
Again, the closed form is direct and professional.
Casual Writing
In casual communication, you may occasionally see re-order.
A text message, forum post, personal note, or informal website may use the hyphen simply because the writer prefers it visually.
The meaning will usually remain clear.
Still, casual writing does not require you to copy every variation you encounter. If you want a reliable default, continue using reorder.
Business and Marketing Content
Business writing benefits from consistent spelling.
Imagine an online store using all three versions across different pages:
- Reorder
- Re-order
- Re Order
That inconsistency can make the content look poorly edited.
A better approach is to establish a style preference and apply it consistently.
For standard American English, that preference will generally be:
reorder
Academic and Editorial Writing
Academic and editorial environments often follow a particular style guide. If your institution, publisher, or employer has a house style, follow it.
If no special instruction exists, reorder is the practical choice for ordinary American English prose.
The same principle applies to related forms:
- reordered
- reordering
- reorders
These forms normally retain the closed spelling.
Case Studies and Pop Culture Examples
Case Study 1: Online Shopping
Imagine an online store where a customer purchases laundry detergent every month.
The website might include a button labeled:
Reorder
This is an excellent example of standard usage because the customer is ordering the same or a similar item again.
A sentence could read:
Click Reorder to purchase the item again.
The closed form works naturally as both a verb and a user-interface label.
Case Study 2: Editing a Document
Now imagine an editor working with a long article.
The editor might tell a writer:
Please reorder these paragraphs so the explanation follows a clearer sequence.
Here, reorder does not mean purchase something again. It means change the arrangement.
This example demonstrates why context matters when interpreting the word.
Case Study 3: Classroom Instructions
A teacher might provide students with five events from a historical timeline.
The instruction could say:
Reorder the events from earliest to latest.
Again, the meaning is to place something in a different sequence.
Case Study 4: Software Interfaces
Modern software frequently lets users drag items into a new sequence.
An application might display an instruction such as:
Drag items to reorder them.
This is another natural use of the closed form.
Case Study 5: Business Inventory
A warehouse manager might write:
We need to reorder the missing products before Friday.
The meaning here is to purchase or request another supply.
Across all five examples, the same spelling remains useful.
Advanced Scenarios and Flowchart
When you encounter reorder or re-order, use this simple decision process:
Start
↓
Do you mean “order again” or “arrange again”?
↓ Yes
Write reorder.
↓ No
Is re- being used as a prefix to create a normal, established English word?
↓ Yes
Check whether the established spelling is normally closed.
↓
If the standard form is closed, use reorder or the appropriate closed form.
↓ No
Could the construction create genuine ambiguity or require special technical clarification?
↓ Yes
Check your dictionary, style guide, or publication rules.
↓
If that source permits or recommends a hyphen, use re-order.
↓
Otherwise, use reorder.
This flowchart highlights an important principle: do not add a hyphen simply because you can see the prefix.
Quick Reference Table
| Form | Status in American English | Typical Use |
| reorder | Preferred standard form | Order again or arrange again |
| reordered | Standard | Past tense or past participle |
| reordering | Standard | Present participle or gerund |
| reorders | Standard | Third-person singular verb |
| re-order | Less common | Occasional clarity or style choice |
| re order | Incorrect in standard usage | Unnecessary separation |
Common Mistakes That Lower Quality
Mistake 1: Assuming Every Re- Word Needs a Hyphen
The prefix re- does not automatically require a hyphen.
Writing re-order simply because you see re + order is unnecessary in ordinary American English.
Mistake 2: Writing Re Order as Two Words
Re order is not the normal spelling.
A prefix should not be separated from its base word with a space.
Use:
reorder
Not:
re order
Mistake 3: Switching Forms Randomly
A document might use reorder in one paragraph and re-order in another.
Even if both forms are understandable, inconsistent spelling makes the document look less polished.
Choose a standard form and maintain it.
Mistake 4: Confusing Reorder With Rearrange
These words can overlap in some contexts, but they are not always interchangeable.
Reorder focuses on changing an existing sequence or ordering something again.
Rearrange emphasizes changing the arrangement or positioning of things.
For example:
Please reorder the steps.
This specifically highlights sequence.
Please rearrange the furniture.
This focuses on physical positioning.
Mistake 5: Assuming the Hyphen Changes the Meaning
In most ordinary contexts, re-order is not a completely separate word with a dramatically different meaning.
The hyphen usually affects presentation rather than creating a new definition.
Mistake 6: Copying an Older Source Without Checking Style
Older books, archived documents, and historical publications may use hyphenation differently.
Do not assume that an older spelling convention represents the preferred spelling today.
Mistake 7: Ignoring Your Organization’s Style Guide
Some companies, publishers, and institutions establish their own conventions.
If your workplace says to use a particular spelling, follow the house style for that publication.
Memory Hacks That Actually Work
Hack 1: Think “Again = Closed”
When re- means again, your first thought should be a closed word.
re + order = reorder
This simple association works for many common words.
Hack 2: Remove the Prefix
Take reorder apart mentally:
re + order
The base word order remains meaningful, and re- adds the idea of doing it again.
Put them together:
reorder
No space. No automatic hyphen.
Hack 3: Use the “Order Again” Test
Ask yourself:
Does this mean “order again”?
If yes, write:
reorder
For example:
I need to reorder the supplies.
You can mentally substitute:
I need to order the supplies again.
The meaning remains clear.
Hack 4: Remember the Family
Put reorder beside familiar closed words:
- rewrite
- rebuild
- reopen
- reconsider
- reorganize
- reorder
Seeing the pattern makes the spelling easier to remember.
Hack 5: Reserve the Hyphen for a Reason
Do not ask:
“Can I put a hyphen here?”
Ask:
“Do I have a specific reason to put a hyphen here?”
If the answer is no, the closed form is usually the better choice.
Why Precision Matters, SEO and Authority
Small spelling decisions can influence how polished your content appears.
A reader may not consciously stop at every hyphen, but consistent language creates a sense of editorial control. This matters particularly for websites, educational resources, business pages, and professional publications.
For SEO content, consistency is also useful because your page should present a clear, natural language pattern. If your target phrase is reorder or re-order, you can discuss both forms without treating them as equally preferred in every context.
A strong article should answer the reader’s actual question quickly.
If someone searches “reorder or re-order”, they want to know which form to use, why the difference exists, and whether the hyphen changes the meaning. Giving a direct answer followed by examples makes the content more useful.
Authority comes from accuracy, clarity, and consistency, not from complicated terminology.
That is why a simple rule can be powerful:
Use reorder as the standard American English form when you mean order again or arrange again.
If you encounter re-order, understand what the writer means, but do not assume that the hyphen is required.
For professional writing, the safest practical approach is to use reorder unless a recognized style guide, dictionary preference, or specialized context gives you a reason to do otherwise.

Conclusion
When deciding between reorder or re-order, the practical rule for American English is clear: reorder is generally the preferred spelling. Use it when you mean to order something again, arrange something again, or change the sequence of existing items. The word works naturally in business writing, academic material, website content, software instructions, everyday communication, and professional documents.
Examples such as “Please reorder the supplies” and “Reorder the paragraphs” follow the standard closed spelling. You do not normally need to insert a hyphen simply because re- is functioning as a prefix.
The form re-order is understandable and may occasionally appear when a writer wants to visually separate the prefix for clarity or follows a particular editorial convention. However, that does not make the hyphen necessary in ordinary writing.
If you are writing for an American English audience and no specific style guide says otherwise, reorder is the safest and most natural choice. Remember the simple pattern: re- + order = reorder. When the meaning is “order again” or “arrange again,” keep the word closed, maintain consistency throughout your content, and avoid unnecessary hyphenation.
Frequently Asked Questions
Is “reorder” one word or two?
Reorder is one word. In standard contemporary American English, you should normally write it as a single word rather than separating re and order. The word can mean ordering something again, such as purchasing another product, or arranging something differently, such as changing the sequence of paragraphs. The form “re order” is not the standard spelling.
Is “re-order” grammatically correct?
Re-order can be understood by readers and may appear in some publications, but the hyphen is generally unnecessary in standard American English. Reorder is the preferred spelling for ordinary writing. A particular publisher, organization, or specialized context might use a different convention, so always follow an applicable house style when one exists.
What does “reorder” mean?
Reorder has two closely related meanings. It can mean to order something again, as when a customer purchases a product they previously bought. It can also mean to arrange something again or change its sequence, as when an editor reorders paragraphs. Context usually makes the intended meaning clear.
Should I use “reorder” in formal writing?
Yes. Reorder is appropriate for formal writing, including academic papers, professional reports, business communication, instructional material, and website content. Unless your publication follows a specific style that recommends re-order, the closed form is the better default. Using the standard spelling also helps keep your writing consistent and polished.
Is “reorder” used only for buying something again?
No. Although reorder commonly refers to placing another purchase order, it can also describe changing the sequence or arrangement of something. For example, “The customer decided to reorder the supplies” means order them again, while “The editor decided to reorder the paragraphs” means arrange them in a different sequence.
Why do some people write “re-order”?
Writers may use re-order. They want to make the prefix re- visually obvious, because they have encountered that spelling elsewhere, or because a particular publication follows that convention. Older sources and specialized writing may also contain different hyphenation practices. However, seeing the hyphen does not mean it is required in modern American English.
Is “reorder” different from “rearrange”?
The words can overlap, but they emphasize slightly different ideas. Reorder usually focuses on changing a sequence or ordering something again. Rearrange more broadly emphasizes changing the arrangement or position of things. You might reorder a list but rearrange furniture. Context determines which verb communicates the intended action more precisely.
What is the past tense of “reorder”?
The past tense is reordered. For example, “The customer reordered the product yesterday” means the customer placed another order. Likewise, “The editor reordered the paragraphs” means the editor changed their sequence. The past-tense form remains closed, without a hyphen between re and ordered.
What is the correct spelling, “reordering” or “re-ordering”?
Reordering is generally the preferred spelling in American English. It is the -ing form of reorder and is normally written as one word. For example, “The team is reordering the information” means the team is changing its sequence. There is usually no need to insert a hyphen into the word.
Is “reorder” the preferred American English spelling?
Yes. Reorder is generally the preferred spelling in contemporary American English when the word means order again or arrange again. While re-order may appear in some contexts, it is less common and normally does not provide a necessary distinction. When no specific editorial rule applies, choosing reorder is the clearest standard option.
