English often creates confusion when prefixes like re- are attached to existing words. One common question is whether you should write reorder as one word or split it into re order. While they may look similar, they aren’t always interchangeable.
The good news is that the answer is straightforward once you understand how English forms words with prefixes. In most situations, reorder is the correct spelling because it functions as a single verb meaning “to arrange again” or “to order again,” depending on the context. Re order, written as two words, is usually incorrect except in very specific writing situations where re functions separately from order.
This guide explains the difference, provides examples, highlights common mistakes, and helps you remember the correct form with confidence.
Quick Answer
Reorder is the standard and correct spelling in modern English. It means to arrange something again or to place another order. Re order is generally incorrect unless re is intentionally separated for stylistic, editorial, or technical reasons. In everyday writing, always choose reorder.
Why People Confuse It
Many English learners become unsure because:
- The prefix re- means “again.”
- Some words appear both hyphenated and closed in different contexts.
- Spell checkers occasionally overlook spacing errors.
- Similar words like re enter and recreate sometimes require hyphens.
- English spelling rules for prefixes are not always consistent.
Since order is already a complete word, some writers mistakenly separate the prefix, producing re order.
Reorder
Reorder is a standard English verb formed by adding the prefix re- to order.
It has two common meanings:
- To arrange something again in a different order.
- To buy or request something again.
Examples
- Please reorder the files alphabetically.
- We need to reorder the inventory this week.
- She decided to reorder the paragraphs for better flow.
- I had to reorder my prescription.
- The teacher asked students to reorder the sentences.
Re Order
Re order is usually not considered correct English.
Separating re from order breaks the word into two unrelated parts. In standard grammar, prefixes attach directly to the base word.
Rare Exceptions
You might occasionally see re order when:
- An editor intentionally separates the prefix for emphasis.
- The word Re: (meaning “regarding”) appears before order in emails or legal documents.
- Example: Re: Order #4567
Notice that this is Re:, not the verb reorder.

Another Common Error

Memory Trick
Think of it this way:
When “re-” simply means “again,” it usually joins the word.
So:
- rewrite ✅
- rebuild ✅
- restart ✅
- reorder ✅
No space is needed.
American vs British English
Both American English and British English prefer reorder as one word.
There is no meaningful regional difference between the two varieties regarding this spelling.

Notice that these prefixes are attached directly to the base word.
Final Verdict
The correct spelling is reorder.
Use it whenever you mean:

Avoid re order in normal writing because it is almost always a spacing error. Following standard spelling makes your writing clearer, more professional, and easier to understand.
