“Revaluation” means to “value something again.” “Re-evaluation” means to “evaluate something again.” The two words are not the same, but when the hyphen isn’t included, they look almost identical.

This is correct and commonly used in English when you want to emphasize the prefix "re-" and separate it from the base word. Use "re-evaluate" when you want to stress the idea of evaluating something again by clearly separating the prefix "re-" from the base word "evaluate".

Both 'reassess' and 'reevaluate' are correct and commonly used in English. They are synonyms that mean to assess or evaluate something again. The choice between them depends on personal preference or the specific context in which they are used.
