This page has lists of the top 10,000 words in each of Dutch, English, French, and German. As the page is in German, I've put together a little table to take you directly to the lists. The lists unfortunately do not have translations.
After the jump, the table and a another word frequency list for French.
|Dutch||Top 100||Top 1,000||Top 10,000|
