This Ebook was designed for beginner and for more advanced level students as well. Even if you’re already familiar with this grammar rule, you’ll still find interesting new words 🙂 Everything is illustrated to help you remember more. For more examples and details, watch my video about this topic.
If you don’t know what’s vowel harmony (back, front vowel groups) I suggest to watch my video about it, to make this Ebook easier to understand.
