My Dictionary app seems to be malfunctioning. When using force touch to look up a word I get an error "content not available" (see photo).
When I open the Dictionary app and search for a word, no definitions populate (see photo).

Problem continues on Guest account as well.
It might be that your Dictionary needs to be updated, look under Dictionary in the menubar and click on Preferences.
There may be a dialogue asking you to update Dictionary and then select the Dictionaries and or Thesaurus you want to use and then drag them into the order you would like them to display.
Open dictionary app and its preferences , did you checked the boxes .
And still it is not finding the meaning of a word , enter in user library macOS Sierra: Library folder
and drag and drop the plist shown on the desktop .
The last final solution is take back up of all data , erase the HD and reinstall OS .
The boxes checked are identical. See photo
Your second instructions to "enter in user library macOS Sierra: Library folderand drag and drop the plist shown on the desktop" is not clear. Your second screenshot is identical to the first. What item in the Library folder do I need to drag and drop?
As you suggested, I moved the file to the desktop and restarted. Problem remains.
Screenshot attached.
By mistake the image was posted two times , enter into the user library , find a folder Preferences > inside it search for com.apple.DictionaryServices.plist to the desktop , restart the machine .
Note : For different Mac ( Like Mac Pro , Mac Book air ) the name of dictionary plist could slightly vary .
, if possible post the screen shot of dictionary plist .
