Would like to see a practice of common nouns
Always difficult to memorize the gender for German nouns. That trips me up all of the time.
As I was learning Italian at university, I used to write words in a little hardcover notebook which fitted into my pocket. Whenever I had a free moment, at a traffic light (riding a bike, one had to wait very long those years), anything, I took out the book and learned. Write nouns with their article and plural down and learn them.
