The translator lets you quickly tanslate from and to almost any language. You can access through text select menu when reading and selected text will be the text to translate :).
By default, if your book identifies its own language, this will be the origin, your local device language will be destination language.
That’s all, just try it! Never was so easy to read in foreign languages.
As in dictionary, you can easily add a note from translator results for later review.
