You’re mid-sentence, typing a professional report or academic paper, and suddenly you freeze is it reevaluation or re-evaluation? One looks too cluttered with vowels; the other feels unnecessarily formal. Both stare back at you from your screen, and neither one looks obviously wrong.
Here’s the good news: both spellings are correct. But that doesn’t mean they’re interchangeable in every situation. The right choice depends on your audience, the style guide you follow, and whether you’re writing for American or British readers. This guide breaks it all down clearly no grammar fluff, just the facts you need.
Is “Reevaluation” or “Re-evaluation” Correct?
The short answer: both forms are grammatically acceptable, but they follow different conventions.
- Reevaluation (no hyphen) is the standard form in American English, backed by Merriam-Webster, the AP Stylebook, and the Chicago Manual of Style.
- Re-evaluation (with hyphen) is the preferred form in British English, aligned with the Oxford English Dictionary and Cambridge Dictionary conventions.
Neither spelling changes the meaning of the word. Both refer to the process of assessing or reconsidering something again whether that’s a plan, a decision, a diagnosis, or a set of results.
What Do Major Dictionaries and Style Guides Say?
| Authority | Preferred Spelling | Region |
|---|---|---|
| Merriam-Webster | reevaluation | American English |
| AP Stylebook | reevaluation | American English |
| Chicago Manual of Style | reevaluation (flexible) | American English |
| Oxford English Dictionary | re-evaluation | British English |
| Cambridge Dictionary | re-evaluation (both accepted) | British English |
| APA (7th edition) | reevaluation | Academic/American |
The pattern is clear. American style guides consistently drop the hyphen. British and international sources tend to keep it.

“Reevaluation” vs “Re-evaluation” in Practice: Usage Examples
Correct Usage Examples
These sentences show both forms used appropriately in context:
American English (no hyphen):
- The board called for a full reevaluation of the company’s pricing strategy.
- After new data emerged, a reevaluation of the policy seemed necessary.
- The teacher will conduct a reevaluation of test results next week.
- A reevaluation of the project timeline is scheduled for Q3.
British English (with hyphen):
- The paper proposes a re-evaluation of existing climate models.
- The patient requires a re-evaluation of symptoms following surgery.
- A re-evaluation of data trends revealed unexpected patterns.
- The committee completed its re-evaluation of the research proposal.
Both sets of examples are correct. The difference is regional and stylistic not a matter of right versus wrong.
Incorrect Usage Examples
There is one form that is always wrong, regardless of style guide or region:
❌ We need a re evaluation of the plan. (two separate words — never correct)
❌ The process of re evaluation took weeks. (prefix separated — incorrect)
❌ Please submit your re evaluation by Friday. (no hyphen, no merge — wrong)
Writing re evaluation as two words is a consistent error. The prefix “re-” is never a standalone word — it must attach directly to the root word, either with or without a hyphen.
Context Variations
The preferred form can shift depending on the professional context:
| Field | Preferred Form | Reason |
|---|---|---|
| News & journalism | reevaluation | AP Style standard |
| Business reports (US) | reevaluation | Corporate American style |
| Academic journals (UK) | re-evaluation | British academic convention |
| Medical documentation | re-evaluation | Clarity-first approach |
| Legal writing | re-evaluation | Formal British/international norms |
| Digital content & blogs | reevaluation | Cleaner for SEO and readability |
| Student essays (US) | reevaluation | APA and Chicago alignment |
Why Do Writers Add or Drop the Hyphen in Reevaluation?
This is where it gets genuinely interesting. The hyphen debate around re- words is not random it reflects how the English language has evolved over the last century.
The Historical Shift in Hyphenation
English hyphenation has been declining steadily for decades. Words that once required a hyphen have gradually fused into single, unhyphenated forms. Think about it: e-mail became email, web-site became website, and re-elect became reelect in most American usage. The same simplification has happened to reevaluation.
This trend is driven by the core principle behind American style guides: use a hyphen only when its absence causes confusion. If readers can understand the word without it, drop it.
The Double-E Problem
One reason many writers still reach for the hyphen in re-evaluation is the awkward double “e” that appears when the prefix and root word join: re + evaluation = reevaluation. Two consecutive e’s can make a word look like a typo at first glance.
However, this double-vowel pattern is perfectly standard in American English. Words like reenter, reelect, reenact, and reestimate all follow the same pattern and none of them require a hyphen in modern American usage.
When the Hyphen Actually Changes Meaning
There is a category of re- words where the hyphen is essential because dropping it creates an entirely different word with a different meaning:
- re-sign (to sign again) vs. resign (to quit a job)
- re-cover (to cover something again) vs. recover (to heal or get better)
- re-create (to create again) vs. recreate (to relax or play)
- re-form (to form again) vs. reform (to improve)
In all these cases, the hyphen is not optional it is necessary for the reader to understand your meaning. Reevaluation, however, does not fall into this category. There is no separate word “revaluation” that could create dangerous confusion.
Note: Revaluation (without the “e”) does exist it means the reassessment of a currency’s value. If your context might cause confusion between reevaluation and revaluation, the hyphenated re-evaluation can serve as a useful visual separator.
How to Remember the Right Spelling
If you write primarily for American audiences, here is a simple three-step rule to follow every time:
- Check the dictionary first. Merriam-Webster lists reevaluation as the primary American English spelling. If it’s there without a hyphen, that’s your default.
- Ask: does removing the hyphen create a different word? If yes (like re-sign vs. resign), keep the hyphen. If no as with reevaluation drop it.
- Pick one form and commit. Once you choose reevaluation or re-evaluation for a document, use the same spelling throughout. Switching between the two in the same piece looks like an editing error, even if both are technically acceptable.
A quick memory trick: American = Attached (no hyphen). British = Break it (with hyphen). That two-word reminder captures the core rule.(Dialect )
FAQs
Is “reevaluation” one word or two?
It is one word. Writing it as two separate words (re evaluation) is always incorrect. It can be written as one closed word (reevaluation) or as a hyphenated word (re-evaluation), depending on your style guide.
Which spelling should I use in an academic paper?
For American academic writing, follow APA or Chicago style and use reevaluation without a hyphen. For British or international journals, re-evaluation is the safer choice.
Does it matter for SEO which spelling I use?
Yes, slightly. Reevaluation has higher search volume in the United States, making it the stronger primary keyword for American-focused digital content. You can include re-evaluation naturally in the body copy for broader keyword coverage.
Will spellcheck flag “reevaluation” as an error?
Some spellcheckers particularly those set to British English may flag reevaluation and suggest the hyphenated form. This is not a true error; it reflects a regional setting. Switching your language setting to US English typically resolves it.
Are “reevaluation” and “revaluation” the same word?
No. Reevaluation means assessing something again. Revaluation is a specific financial term referring to the upward adjustment of an asset’s or currency’s value. They are distinct words with different meanings.
Can I use both spellings in the same document?
Technically both are correct, but mixing them in the same document looks inconsistent and unprofessional. Choose one form and apply it consistently throughout.
Conclusion
The debate between reevaluation and re-evaluation comes down to geography and style, not grammar correctness. If you’re writing for an American audience in business, journalism, academia, or digital content go with reevaluation. It’s cleaner, aligns with Merriam-Webster and major US style guides, and reflects how modern English has evolved.
If your audience is British, international, or your style guide specifically calls for it, re-evaluation is entirely appropriate and professional.
The one rule that applies universally: pick a form and stick with it. Consistency signals careful writing. Inconsistency, even between two technically valid spellings, signals the opposite.
