Description:
Simple dictionary from Swedish to English; it's fast, small and contains about 5,000 entries with several translations.
Further, it has a multiple-choice quiz function to learn the foreign language better; it can be expanded to use other languages as well.
The dictionary is very compact and uses only about 4.7 bytes per word, which has an average length of 11 bytes.
With 5,000 entries, it is not overwhelmingly large, but contains enough vocabulary for the average traveler and polyglot.
