Vocabulary words should be listed with their articles to also study the gender of the nouns!
I'm a French major and I'm using this site to refresh some basic vocabulary. Especially in French, nouns rarely have consistant endings that indicate the gender of the noun. When a French person thinks of "wine" they think of "le vin" NOT just "vin". Having the articles listed on the vocabulary lists also helps when making sentences. One will know easier when to say "du" or "de la" in a sentence. This should be enforced in vocabulary lists!!
This is exactly what I have also been hoping for / wondering about for the German lessons.
The thing I find most difficult is that I literally have to guess the gender of the noun on the first time I'm shown it in a lesson, which seems ridiculous.
I was considering making some flash cards for this, but if there was somewhere on the site to view something similar that would be amazing.
