I've improved the Noun Declinator with better usability, especially for mobile devices.

Key Improvements

Choose Number of Nouns: You can now choose how many nouns you want to practice in each exercise. This gives you more control over the length of your practice sessions. You can even choose one noun to practice different forms of the same noun.

Cześć! Jestem Jarek, miło mi Cię poznać!
(Hello, I'm Jarek, nice to meet you!)
I like learning foreign languages. I've created this website for people like me, who enjoy learning new languages 🙂 I hope my work helped you learn Polish! If you spot a mistake or have a suggestion, I'd love to hear from you.

Cases - Noun Declension

You can support my website and my Youtube Channel by buying my grammar book on Amazon. In that book I have clearly explained, how to create different forms of noun depending on the case, number, and gender.
After reading this book you will be able to decline any noun in the Polish language. This book also contains exercises with answers, which will help you practice what you learn.
