You know what's fun (or "fun", depending on your point of view) about French? Its spelling is so far removed from its pronunciation (I'd say further than in English), that I'm convinced native speakers a lot of the time don't know the correct written grammar. I mean, the spoken French barely has any tenses at all (because letters that would distinguish them are not pronounced)... and there's only traces of articles (apart from very formal speech)... Although this also makes learning written and spoken French two very different undertakings, simply because one rarely helps the other.

German, despite all its conjugations and declensions, is a blessing in this regard. Heard an expression, immediately can use it in a message... It would be appropriate to illustrate the phenomenon here, but I can't recall anything appropriate right now.
