Dictionaries can be deleted from the Client Workspace.
NOTE: If you delete a dictionary from the Client Workspace, all of the learned words in that dictionary will also be deleted.
Open the Dictionaries Dialog
Open the Dictionaries dialog via Settings > Dictionaries in the navigation menu.
Delete a dictionary
Select the dictionary you wish to delete, and click the Delete option in the dictionary's option menu.
NOTE: It is possible to select and delete multiple dictionaries at once, if required.
If the information in the confirmation dialog looks correct, click Yes to delete the selected dictionaries.
