Hi Barbara,
Good day. First check is if the Editor is actually enabled for the document.
- In Word, go to Home > Editor and wait a few seconds for it to finish checking.
- If it still doesn't flag obvious spelling or grammar issues, go to File > Options > Proofing.
- Make sure Check spelling as you type and Mark grammar errors as you type are enabled.
- Also check Exceptions for: and make sure Hide spelling errors in this document only and Hide grammar errors in this document only aren't selected.
- Close Word completely, reopen the document, and test Editor again.
By the way, if Editor works in a new blank document but not in this particular file, the issue may be specific to that document or its language settings. In that case, check Review > Language > Set Proofing Language and make sure the correct language is selected and Do not check spelling or grammar isn't enabled.
I hope this helps.
Regards,
Jhun
