Reevaluation or re-evaluation—which spelling should you use? If you have ever hesitated over the two e’s in reevaluation, you are not alone. The confusion is understandable because re- means “again,” while evaluation already begins with e, producing the visually unusual combination ree-. The good news is that the two forms generally have the same meaning: evaluating, examining, or considering something again. Major dictionaries recognize both forms, although their preferred headwords and regional conventions can differ.
In practical writing, the important distinction is therefore spelling and editorial style rather than meaning. Merriam-Webster lists reevaluate as the main entry and gives re-evaluate as a variant; for the noun, it likewise lists reevaluation and re-evaluation. Cambridge does the reverse in its entries, listing re-evaluate and re-evaluation while explicitly noting reevaluate and reevaluation as alternatives.
This guide explains reevaluation vs. re-evaluation from a beginner-friendly but editorially precise perspective. You will learn why the spellings vary, whether re-evaluation is correct, how American and British usage can differ, which form to choose in professional or academic writing, and how to keep your document consistent. By the end, you will have a simple rule you can apply whenever this spelling question comes up.
Reevaluation vs. Re-Evaluation: The Quick Answer
Both reevaluation and re-evaluation are established English spellings for the noun meaning the act or process of evaluating something again.
The practical answer is:
Use “reevaluation” as a strong default in American English, unless your style guide, organization, or publication prefers “re-evaluation.”
This recommendation is supported by current dictionary treatment. Merriam-Webster’s entry uses reevaluate as its main form and identifies re-evaluate as a variant; its noun entry likewise gives reevaluation with re-evaluation as a variant.
Cambridge, meanwhile, lists re-evaluation as its noun entry and explicitly identifies reevaluation as another form. Its entry defines the word as the process of judging or calculating something again.
So there is no useful general rule such as “one is correct and the other is wrong.”
The three forms at a glance
| Form | Meaning | Practical verdict |
| reevaluation | Evaluation again | Preferred default in many American-English contexts |
| re-evaluation | Evaluation again | Established variant; appropriate where style favors it |
| re evaluation | Evaluation again | Generally avoid when intended as one prefixed word |
The key point is simple: the hyphen does not normally change the meaning.
What Does “Reevaluation” Mean?
Reevaluation is the process of evaluating, examining, judging, or considering something again.
The word is formed from:
- re- = again
- evaluation = the act of assessing something
So:
re- + evaluation → reevaluation
Merriam-Webster defines reevaluate as evaluating someone or something again, particularly in light of changes or new information, and lists reevaluation as the corresponding noun.
The idea of “again” does not necessarily mean the original evaluation was wrong. A second evaluation may simply be necessary because circumstances, evidence, priorities, or available information have changed.
Examples of “reevaluation”
- The committee called for a reevaluation of the policy.
- New evidence led to a reevaluation of the original conclusion.
- The company is conducting a reevaluation of its long-term strategy.
- The student’s progress prompted a reevaluation of the learning plan.
- The new data requires a reevaluation of the earlier assumptions.
Notice that reevaluation is a noun. It names the process or event, rather than describing the action directly.
Compare:
- Verb: The committee will reevaluate the policy.
- Noun: The committee will conduct a reevaluation of the policy.
That distinction becomes useful when choosing between reevaluate and reevaluation.
What Does “Re-Evaluation” Mean?
Re-evaluation means essentially the same thing as reevaluation: an evaluation performed again.
Cambridge defines re-evaluation as the process or act of judging or calculating the quality, importance, amount, or value of something for a second or subsequent time. It also explicitly lists reevaluation as another form.
Oxford’s Advanced Learner’s Dictionary likewise lists re-evaluation as a noun meaning the act of thinking about something again, particularly to form a new opinion.
Examples of “re-evaluation”
- The project requires a re-evaluation of its original goals.
- The findings prompted a re-evaluation of the theory.
- Management announced a re-evaluation of its hiring strategy.
- The report recommends a re-evaluation of current procedures.
- The discovery triggered a re-evaluation of the evidence.
The hyphen makes the relationship between re- and evaluation visually obvious, but it does not normally create a different definition.
Is “re-evaluation” wrong?
No. Calling re-evaluation simply “incorrect” ignores how reputable dictionaries actually treat the word.
The better editorial explanation is that both spellings are established, but different dictionaries, regions, and style systems may favor different forms. Merriam-Webster currently presents the closed form as its main entry, while Cambridge presents the hyphenated form as its headword.
That distinction matters when you’re editing professionally: preferred form and valid form are not always the same thing.
Reevaluation vs. Re-Evaluation: What Is the Real Difference?
For ordinary English usage, the difference is primarily orthographic—that is, it concerns how the word is written.
| Feature | Reevaluation | Re-Evaluation |
| Basic meaning | Evaluating again | Evaluating again |
| Word formation | re- + evaluation | re- + evaluation |
| Hyphen | No | Yes |
| Dictionary recognition | Yes | Yes |
| Meaning normally changes? | No | No |
| Best general approach | Use according to style | Use according to style |
| American-English default | Often a good choice | Also established |
| British/international writing | Depends on dictionary/style | Commonly encountered |
Meaning does not usually change
Consider these sentences:
The board ordered a reevaluation of the proposal.
The board ordered a re-evaluation of the proposal.
A normal reader will understand both as saying that the proposal should be evaluated again.
The hyphen does not ordinarily signal a different kind of evaluation.
That is why articles that present these as two completely different words can create more confusion than they solve.
Why Does “Reevaluation” Have Two E’s Together?
This is probably the biggest visual reason people hesitate.
The word is built from:
re- + evaluation
The final letter of re- is e, while evaluation begins with e. Put them together and you get:
reevaluation
That can look strange because English readers are accustomed to seeing many prefixes attached to words without such a conspicuous vowel sequence.
But unusual-looking does not mean incorrect.
Merriam-Webster’s current entry explicitly recognizes reevaluate and reevaluation, confirming that the closed forms are established dictionary spellings.
Does a double vowel require a hyphen?
No.
There is no universal English rule saying that a prefix must be separated whenever two identical vowels meet.
English spelling conventions are more complicated than “two vowels together = add a hyphen.” Some prefixed words are conventionally closed, some retain a hyphen, and some forms can vary according to dictionary, region, or editorial style.
That is why the safest approach is not to invent a mechanical rule. Check the established spelling and follow the style system relevant to your audience.
How the Prefix “Re-” Works
Understanding re- makes the spelling easier to remember.
The prefix re- commonly expresses the idea of:
- doing something again
- returning to an earlier state
- repeating an action
For example:
- reconsider = consider again
- reassess = assess again
- reexamine = examine again
- revisit = visit or consider again
- reevaluate = evaluate again
The exact spelling of each word is determined by English usage rather than by simply applying one universal punctuation formula.
Reevaluate vs. Re-Evaluate
The same variation appears with the verb:
- reevaluate
- re-evaluate
Cambridge lists re-evaluate and notes reevaluate as another form. Merriam-Webster lists reevaluate as the main entry and gives re-evaluate as a variant.
So the noun variation is part of a broader spelling pattern:
| Verb | Noun |
| reevaluate | reevaluation |
| re-evaluate | re-evaluation |
A useful editorial rule is to keep the forms coordinated. If your chosen style uses the closed verb, the corresponding closed noun will usually provide the cleanest consistency.
When Should You Use “Reevaluation”?
Choose reevaluation when it fits the spelling convention you are following and you do not have a house style requiring the hyphen.
It works naturally in:
Academic writing
The findings prompted a reevaluation of the original hypothesis.
Business writing
The company began a reevaluation of its pricing strategy.
Workplace communication
We need a reevaluation of the current workflow before expanding the program.
General writing
The experience led to a reevaluation of her priorities.
The closed form is particularly convenient when the word appears repeatedly throughout a report because it keeps the typography compact.
Expert recommendation
If you’re writing in American English without a specific house style, reevaluation is a sensible default. It is the primary form in Merriam-Webster’s current entry, although the dictionary also recognizes re-evaluation.
When Is “Re-Evaluation” a Good Choice?
There are situations where re-evaluation makes perfect editorial sense.
When your style guide prefers it
A publisher, university, company, or professional organization may have its own spelling conventions. If its style sheet consistently uses re-evaluation, follow that preference.
When you’re maintaining an established document style
Suppose a report already uses:
- re-evaluate
- re-evaluation
- re-examine
Changing only one word may create unnecessary inconsistency.
In editing, internal consistency is often more useful than imposing your personal spelling preference.
When the hyphen improves visual readability
The hyphen can make the word’s structure immediately visible:
re-evaluation
The reader can instantly see:
re- + evaluation
That can be a legitimate stylistic reason, although it should not be mistaken for a grammatical requirement.
What About “Re Evaluation”?
This is where the answer becomes much clearer.
When you mean the noun evaluation again, writing:
re evaluation
as two separate words is generally not the standard choice.
The problem is that re- is a prefix here, not an independent word modifying “evaluation.”
Compare the forms
| Spelling | Example | Verdict |
| reevaluation | We need a reevaluation of the plan. | Standard |
| re-evaluation | We need a re-evaluation of the plan. | Established variant |
| re evaluation | We need a re evaluation of the plan. | Generally avoid |
The first two forms treat the expression as one lexical unit. The third incorrectly separates the prefix from its base word in ordinary usage.
American English vs. British English
One of the easiest mistakes to make is turning regional tendencies into absolute rules.
It is tempting to say:
American English = reevaluation
British English = re-evaluation
That is too rigid.
The actual dictionary evidence is more nuanced.
Merriam-Webster uses reevaluate and reevaluation as its principal entries while recognizing the hyphenated variants.
Cambridge uses re-evaluate and re-evaluation as its entries while explicitly recognizing the closed forms as alternatives.
So the better conclusion is:
Regional and editorial preferences can influence which form you see, but neither spelling should be treated as belonging exclusively to one variety of English.
This is especially important for international websites and academic publications, where a single publication may follow a particular house style regardless of the writer’s location.
Reevaluation vs. Re-Evaluation in Professional Writing
Professional writers often care about something beginners overlook: consistency across the entire document.
Imagine a 40-page report that contains:
- reevaluation on page 2
- re-evaluation on page 17
- reevaluation on page 29
None of these individual spellings necessarily creates a meaning problem. But the inconsistency can make the document look insufficiently edited.
A better editorial workflow
When editing a document:
- Decide which spelling authority you’re following.
- Search the document for reevaluation.
- Search separately for re-evaluation.
- Check whether the variations are intentional.
- Standardize them where appropriate.
- Repeat the process for reevaluate and re-evaluate.
This is especially useful for:
- academic papers
- business reports
- websites
- books
- technical documentation
- institutional publications
Editorial tip: Don’t “correct” a hyphenated form automatically just because you personally prefer the closed form. First determine which style the document is supposed to follow.
Real-World Examples of Reevaluation and Re-Evaluation
Business strategy
The changing market conditions prompted a reevaluation of the company’s strategy.
The word refers to examining the strategy again because circumstances changed.
Academic research
The new evidence led to a re-evaluation of the earlier interpretation.
Here, the focus is on reconsidering an existing interpretation.
Workplace performance
The manager recommended a reevaluation of the team’s workflow.
The second assessment may identify inefficiencies or new priorities.
Public policy
The findings have encouraged a reevaluation of the existing policy.
The policy is being examined again, not necessarily rejected.
Personal decision-making
Moving to another city caused him to reevaluate his priorities.
Notice that the verb is used here. The corresponding noun would be:
Moving to another city caused a reevaluation of his priorities.
Scientific context
The new measurements prompted a reevaluation of the earlier model.
Again, reevaluation identifies the process of examining the model again.
Reevaluation, Reassessment, Reconsideration, and Review: Are They the Same?
Not quite.
These words overlap, but their nuances can differ.
| Word | General idea | Typical nuance |
| reevaluation | Evaluate again | A fresh assessment, often using new information |
| reassessment | Assess again | Often emphasizes judging a situation or condition anew |
| reconsideration | Consider again | Often focuses on changing or revisiting a decision or opinion |
| review | Examine again | Broad and flexible; can involve checking rather than changing a judgment |
| reexamination | Examine again | Often emphasizes detailed or systematic examination |
Cambridge’s thesaurus associates reevaluation with words such as review, examination, reassessment, reconsideration, scrutiny, and study.
That does not mean the words are interchangeable in every sentence.
For example:
The committee requested a review of the report.
is broader than:
The committee requested a reevaluation of the report’s conclusions.
The second sentence more strongly suggests that the existing judgment itself is being assessed again.
Common Mistakes With “Reevaluation”
Mistake 1: Treating “reevaluation” as a spelling error
The two e’s are legitimate.
Correct: The decision requires a reevaluation.
Merriam-Webster explicitly lists reevaluation as the noun corresponding to reevaluate.
Mistake 2: Assuming “re-evaluation” has a different meaning
Usually, it does not.
The hyphen is primarily a spelling/style difference.
Mistake 3: Writing “re evaluation”
If re- functions as a prefix, don’t normally separate it with a space.
Mistake 4: Applying a “double vowel” rule mechanically
Two adjacent vowels do not automatically require a hyphen. Established word forms determine the spelling.
Mistake 5: Mixing styles without a reason
Using reevaluation and re-evaluation interchangeably throughout the same article may make the writing look unedited.
Mistake 6: Confusing “reevaluate” with “reevaluation”
Remember the part of speech:
- reevaluate = verb
- reevaluation = noun
We should reevaluate the proposal.
We should conduct a reevaluation of the proposal.

Re-Evaluate and Re-Evaluation
These are the corresponding hyphenated variants recognized by major dictionaries. Cambridge explicitly treats the hyphenated and closed forms as alternatives, while Merriam-Webster does the same from the opposite headword direction.
A Useful Memory Trick
If you’re writing for an American-English audience and have no special style requirement, remember:
“Reevaluation” is one word with two e’s.
Don’t let the unusual appearance persuade you that it must be hyphenated.
A second trick is to think about the word’s construction:
RE + EVALUATION = REEVALUATION
The two e’s are not an accident. They come from the end of the prefix and the beginning of the base word.
If your publication prefers a hyphen, however, re-evaluation is a legitimate alternative. The memory trick should help you understand the spelling—not force you to ignore an established style guide.
Expert Writing Tips for Reevaluation vs. Re-Evaluation
For polished writing, the biggest issue isn’t choosing the “prettiest” spelling. It is choosing deliberately and consistently.
For general readers
Use the form that matches the dominant style of your publication.
For academic writers
Check your institution’s required style guide before standardizing the spelling.
For editors
Don’t make a blanket change without checking the document’s style system.
For website owners
Choose one preferred form for your site’s editorial style, but naturally mention the alternative when the article is specifically answering a spelling question.
For SEO writers
Don’t repeatedly alternate between the two spellings just to capture search variations. A useful article can naturally explain that reevaluation and re-evaluation are established variants, then consistently use its chosen form.
Search optimization should support clarity, not interfere with it.
Conclusion:
When choosing between reevaluation and re-evaluation, don’t look for a difference in meaning that usually isn’t there. Both forms refer to evaluating, examining, or considering something again, and major dictionaries recognize both. In general American writing, reevaluation is a practical default, while re-evaluation remains an established variant that may fit a particular regional or editorial style. Re evaluation, by contrast, is normally best avoided when re- is functioning as a prefix. One final actionable tip: choose your preferred form before editing a document and use it consistently. A common mistake to avoid is changing a legitimate variant simply because it looks unfamiliar. Good editing is not about forcing every word into one pattern; it is about following accepted usage, respecting context, and making deliberate choices.
FAQs
Q1. Is “reevaluation” or “re-evaluation” correct?
Both forms are established. Merriam-Webster lists reevaluation as the main noun form and re-evaluation as a variant, while Cambridge lists re-evaluation and identifies reevaluation as an alternative. Your preferred form should depend on the dictionary, regional, or house style.
Q2. Is “reevaluation” one word or two?
Reevaluation is normally one word. It combines the prefix re- with evaluation. Writing re evaluation with a space is generally not the standard spelling when you mean “evaluation again.” The established alternatives are reevaluation and re-evaluation, not the spaced form.
Q3. Does “reevaluation” mean the same as “re-evaluation”?
Yes. In ordinary English, reevaluation and re-evaluation have the same basic meaning: evaluating or considering something again. The difference is mainly the presence or absence of a hyphen. Dictionary treatment confirms that the forms are variants rather than separate concepts.
Q4. Should I use “reevaluation” in American English?
As a practical default, reevaluation is a strong choice for American English when no specific house style applies. Merriam-Webster uses it as the principal form while recognizing re-evaluation as a variant. Always follow a required publication or institutional style guide first.
Q5. Why does “reevaluation” have two e’s together?
Because the word combines re-, meaning “again,” with evaluation, which begins with e. The result is reevaluation. English does not require a hyphen simply because two identical vowels meet, so the double-e spelling is perfectly legitimate.
