I have installed some dictionaries.
What is the application to use ?
Gnome dictionary and Artha are also installed but both just give English definitions to English words.

After installing it in Synaptic Manager and also the dictionaries as in the image from the question, start Goldentict and it will read the database.
After in opens all those separate dictionaries appear in it
When selecting a dictionary on that bar it takes some time to load. The quality of these supplementary dictionaries is usually mediocre.
