User dictionary
User Dictionary in the machine translation systems is a dictionary which you can create and update yourself. If you want to add new words to the dictionary or modify the existing entries from the General or specialized dictionaries, you can do it in your own user dictionary. The amount of user dictionaries is not limited.
All new and changed entries can be stored ONLY in the user dictionaries!
If you want to use the meanings from your user dictionary during translation, it should be attached and with the highest priority (that means that this dictionary should be placed the first in the list of attached dictionaries).
