Reevaluation vs Re Evaluation: Which Spelling Is Correct?

Many English learners are unsure whether the correct spelling is reevaluation or re evaluation. The confusion arises because the prefix re means “again,” and some people wonder if it should be written as a separate word before evaluation.

In modern English, however, there is a standard spelling that is preferred in most dictionaries and style guides.

Understanding the difference between reevaluation vs re evaluation will help you write more accurately in academic papers, business reports, emails, and everyday communication. This guide explains the correct spelling, usage, examples, and common mistakes.

Quick Answer

Reevaluation is the correct and standard spelling. Re evaluation is incorrect because the prefix re- should not be separated from the word evaluation. In some style guides, re-evaluation with a hyphen may also be acceptable, but reevaluation is the most common modern form.

Why People Confuse It

The confusion happens because the prefix re- is sometimes written with a hyphen, such as re-enter or re-examine.

As a result, some learners mistakenly separate the prefix completely and write re evaluation, which is not standard English.

Reevaluation

Reevaluation is the correct spelling.

Meaning
