Kannada is a Dravidian language spoken in southern India, primarily in Karnataka.
It has an alphasyllabary script, typical of languages of India.
This app is designed to help you become comfortable with recognizing more and more complex letter forms until you can read and construct full-words.
Start first by studying the vowels, practicing writing them down and then trying the quiz. Then try the quiz with the diacritics.
Then, move on to consonants. This may take more time, as there are many consonants. Then, try the quiz with the consonant-vowel ligatures.
Finally, try the quiz with the conjunct consonants. There are many, many combinations possible, so dont worry about memorizing them all. Some of them are extremely rare.
The word scramble game also has various levels so that you can incrementally test yourself, starting from just the first few consonants. The last level, common words, is a good final test of your abilities.
You can also try the typing game if you have a Kannada keyboard installed on your phone.
