Reevaluation vs Re Evaluation: Which One Is Correct?

English spelling can be confusing, especially when prefixes combine with existing words. One common question writers ask is whether they should write reevaluation as one word or separate it into re evaluation. While both forms may occasionally appear, they are not equally accepted in modern English.

If you’re writing an email, academic paper, business report, or blog post, choosing the correct spelling improves clarity and professionalism. In this guide, you’ll learn the difference between reevaluation and re evaluation, why people confuse them, when each form is appropriate, and how major style guides treat these spellings. By the end, you’ll know exactly which version to use with confidence.

Quick Answer

Reevaluation is the correct and standard spelling in modern English. It combines the prefix re- (meaning “again”) with evaluation into one word. Re evaluation is generally considered incorrect unless a specific formatting or editorial reason requires separating the words.

Why People Confuse It

Many English words beginning with re- create uncertainty because the prefix is attached to another word.

People become confused because:

• The base word already starts with e, creating a double vowel (reevaluation).
• Some older publications occasionally inserted a space.
• Hyphenated forms like re evaluate are more common than reevaluate, making people expect a similar pattern.
• Spell checkers sometimes fail to flag spacing errors.

Although the double ee may look unusual, it is perfectly correct.

Reevaluation

Reevaluation is a noun that means the act of evaluating something again after reviewing new information, evidence, or circumstances.

Meaning

A fresh assessment or renewed judgment.

Examples

• The company announced a reevaluation of its hiring policy.
• Doctors recommended a reevaluation after six months.
• The teacher completed a reevaluation of the student’s progress.
• Market conditions required a full reevaluation of the investment strategy.

Why It’s Correct

The prefix re- is attached directly to the noun evaluation, forming one standard compound word recognized by modern dictionaries.

Re Evaluation

Re evaluation consists of two separate words.

In standard English, this spelling is not recommended.

You may occasionally encounter it in:

• Older printed documents
• Poorly edited websites
• Formatting errors
• Rare situations where re is intentionally separated for emphasis

For everyday writing, academic work, business communication, and professional publishing, avoid this form.

✅ Reevaluation is scheduled tomorrow.

❌ We need a re evaluation of the proposal.
✅ We need a reevaluation of the proposal.

❌ The report recommends re evaluation.

Memory Trick

Think of reevaluation as doing an evaluation again.

The prefix re- almost always joins directly with the base noun.

Re + evaluation = reevaluation

Even though the double ee looks unusual, it is completely correct.

American vs British English

Both American English and British English use reevaluation as the preferred spelling.

There is no meaningful regional difference between the two varieties of English.

Some publishers may choose re evaluation for readability in certain style guides, but re evaluation with a space is generally avoided.

Similar Words

• Reexamination
• Reeducation
• Reemployment
• Reenactment
• Reentry (or re entry depending on style guide)
• Reassessment
• Reconsideration
• Reanalysis
• Reinspection

Notice that many words beginning with re- either become one word or occasionally use a hyphen depending on editorial style but they are rarely written as two separate words.

Final Verdict

The correct spelling is reevaluation.

Use reevaluation whenever you mean evaluating something again. It is the accepted spelling in dictionaries, professional writing, academic work, and everyday English.

Avoid re evaluation because it is generally considered a spacing error rather than an accepted alternative.

Reevaluation is the standard, dictionary approved spelling used across professional, academic, and everyday writing. Although the double ee may look unusual at first glance, it is grammatically correct and widely accepted.
