Dictionary App is not working. Mac OS X-El Capitan 10.11

I was trying to add some new dictionaries

And have you removed those dictionaries?

For .plists, try your user Library, not the hard drive level Library.

Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library.

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

The title of the Console window should be All Messages. If it isn't, select

SYSTEM LOG QUERIES ▹ All Messages

from the log list on the left. If you don't see that list, select

View ▹ Show Log List

from the menu bar at the top of the screen.

Click the Clear Display icon in the toolbar. Then take an action that isn't working the way you expect. Select any lines that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.

Please don't indiscriminately dump thousands of lines from the log into this discussion.

Please don't post screenshots of log messages—post the text.

Some private information, such as your name or email address, may appear in the log. Anonymize before posting.

When you post the log extract, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

Back up all data.

Quit Dictionary if it's running. Test after taking each of the following steps that you haven't already taken. Stop when the problem is resolved.

Step 1

Hold down the option key and select Go ▹ Library from the Finder menu bar. From the Library folder, move the following subfolder, if it exists, to the Trash:

Containers/com.apple.Dictionary

Step 2

Move this subfolder to the Desktop in the same way:

Dictionaries

Log out or restart the computer. If there's no change, put the folder back where it was.

Step 3

Please back up all data, then open the iCloud pane in System Preferences. If the box marked iCloud Drive is checked, uncheck it and confirm. Your iCloud data should be preserved on Apple's servers.

Test to see whether there's an improvement, then re-check the box and test again. It may take a noticeable amount of time for your iCloud Drive data to resynchronize.
