Hello Lawrence, thanks for posting in the community.
Kindly start by checking if the proofing language in Word is set correctly, because the spellcheck will not work when the text is marked as “Do not check spelling or grammar.” You can highlight your text, open the Review tab, select Language, and choose Set Proofing Language, then make sure the option to not check spelling is turned off. After that, go to File, open Options, select Proofing, and confirm that “Check spelling as you type” and “Mark grammar errors as you type” are both enabled. If the problem continues, try repairing Office 2021 through the Control Panel by choosing Microsoft Office 2021 and running a Quick Repair, as this can fix missing or damaged proofing tools. Once the repair is done, restart Word and test the spellcheck again.
Kind regards,
John Oli
