Enter your search term(s) in the search field and tap the search button.

The auto-complete list provides suggestions while you type, the flag to the left indicates the source language. Tap a suggested word to start a dictionary search.

If there are no or only few matches for your search term(s), results may include orthographically similar entries to allow for spelling mistakes.

If the dictionary includes entries for a search term in both languages, the search direction is determined by which language has more entries. In case you’d like to specify a search direction, select your source language from the auto-complete list.

Save to trainer (iPhone) 

Select the translation of your choice and then "Click to save".

Please note: when you save an entry you can only save the word pair. You cannot save the search term on its own (such as “dictionary”) as our system is unable to tell whether you would like to save “Wörterbuch – dictionary” or “Wörterbuch – lexicon”.
