Program to learn German articles.

[PhilOfPerth]

Just a note for those who want to learn German grammar: In German there is no fixed rule for the use of articles, one just have to know it (learn it by heart). 

Mark Twain - The Awful German Language

Surely there is not another language that is so slip-shod
and systemless, and so slippery and elusive to the grasp.
One is washed about in it, hither and hither, in the most
helpless way; and when at last he thinks he has captured a
rule which offers firm ground to take a rest on amid the
general rage and turmoil of the ten parts of speech, he
turns over the page and reads, “Let the pupil make careful 
note of the following exceptions."
He runs his eye down and finds that there are more exceptions 
to the rule than instances of it.

I think Mark Twain overlooked the English language! For every "rule" there are at least 10 exceptions, in both spelling and grammar. This is because English is such a bastardisation of so many other languages - including, among others, German, French, Latin, and Greek. I refer you to the English page on the website in my signature.
