Reevaluation vs Re Evaluation: Which Spelling Is Correct?

When you want to describe the process of evaluating something again, you may wonder whether the correct spelling is reevaluation or re evaluation. The confusion usually comes from the prefix re-, which means “again” or “back.” Since prefixes are sometimes written separately in English, it can be tempting to write re evaluation as two words.

In standard modern English, however, reevaluation is the preferred spelling when the word means a second or renewed evaluation. It is formed by adding the prefix re- to evaluation. You may also encounter the hyphenated form re-evaluation, particularly when writers want to make the word easier to read. Understanding this spelling difference is useful for students, professionals, editors, and anyone writing formal English. In this guide, we’ll compare reevaluation vs re evaluation, explain the grammar behind the spelling, and provide practical examples so you can confidently choose the right form.

Quick Answer

Reevaluation is the standard one-word spelling. Re evaluation is generally incorrect when referring to the process of evaluating something again. Re-evaluation is also accepted in some style guides, but reevaluation is the most common modern form.

Why People Confuse It

The confusion comes from the prefix re-, which means again.

English has many words beginning with re-:

• reconsider
• review
• reconsideration
• reassessment
• reevaluate
• reevaluation

Because evaluation is already a complete word, some writers instinctively separate the prefix and write re evaluation.

Another reason is pronunciation. The word can sound as though it contains two separate parts: re + evaluation. However, pronunciation does not determine whether a compound word should be written as one word.

The key point is simple: re- is a prefix, not normally a separate word in this construction.

First Word: Reevaluation

Reevaluation is the standard spelling when you mean the act of evaluating something again.

It is a noun formed from reevaluate:

re- + evaluation = reevaluation

For example:

The committee requested a reevaluation of the proposal.

Here, reevaluation means that the proposal will be examined or judged again.

Definition of Reevaluation

Reevaluation means:

• a second evaluation
• a renewed assessment
• another examination of something
• reconsideration based on new information

Examples

• The patient required a reevaluation after several weeks.
• The company conducted a reevaluation of its marketing strategy.
• New evidence led to a reevaluation of the original decision.

Second Word: Re Evaluation

Re evaluation is generally not the standard spelling when re- means “again.”

The problem is that re- functions as a prefix and normally attaches to the word that follows it.

So instead of:

❌ re evaluation

write:

✅ reevaluation

You may occasionally see re evaluation in informal writing, unusual formatting, or situations where re has been treated as an independent element, but it is not the preferred standard spelling for this meaning.

What About “Re-Evaluation”?

The hyphenated form re-evaluation can also be found and is understandable.

For example:

The project is undergoing a re-evaluation.

However, modern English commonly favors reevaluation as the closed compound.

For consistency in most general and professional writing, reevaluation is an excellent choice.

Common Mistakes

1. Writing “Re Evaluation”

This is the most common mistake.

❌ The company needs a re evaluation.

✅ The company needs a reevaluation.

2. Assuming Every “Re” Is a Separate Word

The prefix re- usually attaches directly to the base word.

❌ re consider

✅ reconsider

❌ re assess

✅ reassess

❌ re evaluate

✅ reevaluate

3. Mixing Spellings

Avoid switching between reevaluation, re-evaluation, and re evaluation randomly within the same document.

Choose the standard form that fits your writing style and use it consistently.

4. Confusing “Reevaluation” With “Review”

Although the words can have similar meanings, they are not always interchangeable.

A review can mean examining something generally, while a reevaluation specifically emphasizes evaluating it again.

Memory Trick

Think:

RE = AGAIN

Then connect it directly to evaluation:

RE + EVALUATION = REEVALUATION

So remember:

Again + evaluation = reevaluation

If you see re evaluation, ask yourself:

“Is re- being used as a prefix meaning ‘again’?”

If the answer is yes, combine it with the word:

reevaluation ✅

American vs British English

There is generally no major difference in meaning between American and British English when it comes to reevaluation.

Both varieties use reevaluation and reevaluate.

You may also encounter the hyphenated forms re-evaluation and re-evaluate, depending on the publication, dictionary, or editorial style being followed.

The important distinction is that re evaluation as two separate words is not normally the preferred standard spelling.

For professional writing, reevaluation is a safe and natural choice.
