On the right, you'll see words' definitions and/or translations.

You can also enable the "Scan" mode in Ultimate Dictionary, which makes the dictionary follow the mouse and displays a pop-up window with the definition of the word right below the cursor.Ultimate Dictionary is easy to use and performs very fast searches. You can also customize the order in which dictionaries appear, so that you can have your most frequently ones on top
