This dictionary contains more than 90'000 German words and their English translations. To help you pronouncing the German word each article also contains the word written in the International Phonetic Alphabet (IPA). And that's how you can use this dictionary:
1) As a stand alone dictionary. This works on all the Kindle book readers. Open it just like any other book and use to book internal search to find the word you would like to translate. Since you can't enter umlauts on your Kindle yet just use the same letter without the Umlaut sign, e.g. a instead of ä. The reader will present you with a list of hits from which you can choose the right word.
2) As primary dictionary (only on the Kindle device). After the installation (see below) you can use the 5-way button to navigate the text marker to any word to see the English translation.
