On my MacBook Pro 16 inch, the built-in dictionary app stops working on some of the built-in dictionaries, like Oxford Chinese Dictionary, Oxford Thesaurus of English etc. (I cannot select the dictionary options from Preferences)
How could I reinstall the dictionary app?
Thanks!
MacBook Pro 16", macOS 10.15
Thank you for your reply. You put me on to the right track to resolve this.
This problem appears to be isolated to new 16" MBP because they are apparently running a special (???) build of Catalina whether upgraded to 10.15.2 or not.
Here is the solution without the need for a reinstall:
/System/Library/AssetsV2/PreinstalledAssetsV2/InstallWithOs/com_apple_MobileAsset_DictionaryServices_dictionaryOSX
/System/Library/AssetsV2/com_apple_MobileAsset_DictionaryServices_dictionaryOSX
Viola!!

Yes, you are right.
I searched for .dictionary and deleted all the *.dictionary files. Now it works fine.
Actually, before this, I also tried reinstall the whole system, but no luck.
The reason I would like to reinstall is that, I also have another issue:
connecting an external monitor for days, when unlocking the screen from black screen, the laptop monitor keeps flashing and external one stops working. However, after restarting, it is all good again. I hope the reinstallation could fix this together. However, again, no luck!
Hello Siaoming and welcome to Apple Support Communities.
I see you're having an issue accessing some of the built-in dictionary sources on a new MacBook Pro.
Dictionary User Guide for Mac - Apple Support
While it's possible to add additional dictionary sources, the dictionary app itself is part of macOS and can't be reinstalled on it's own.
Reinstall apps that came with your Mac - Apple Support
Cheers.
I have this exact same issue.
I do not wish to go through the process of reinstalling on a new clean 16" MBP
Rather I wish to know how to remove the corrupt downloaded dictionaries so that they can be reselected again.
Experiencing similar problems. Did you find any solution...?
Yes, I posted above ... just follow it
