The problem with inter-lingual dictionaries is... that translations don't always work in both directions. I can understand that some poor souls will have to translate some ungrammatical, poorly-phrased, slang-ridden stuff in another language, into good grammatical German; but how do you tell people not to follow the same bad example, when translating good German back into that other language?

"Zwischen Spräche Wörtenbücher" seems awfully cumbersome.
