I'm looking for a Free-ware on Mac OS X.6 that helps improving English vocabulary, very simply, for example by giving a word in another language (German or French would be perfect) and asking for the translation. It doesn't have to be a nice design or stuff, just simple and efficient. If anyone knows something like that, please let me know!!
EDIT: I'm looking for some kind of "evaluating program", something that tests your vocabulary, not a translator. Maybe I didn't make my question clear.
Thanks in advance.
