Why is the Kannada language compared to Kasturi (musk)?
If you want to compare it with Jasmine, you can!
Poets called it Kasturi Kannada. You cannot ask why they named it so.
For example, a beautiful woman is called ‘Chandramukhi’, meaning the one whose face is like the moon.
Now, the moon has a lot of spots in it. So, why is the face compared to the moon?
There is a saying where it is mentioned that the moon looks like a Holige (a round pancake-like sweet dish in Karnataka) for one who is hungry.
Musk has a very good fragrance. So, poets have described Kannada as a sweet language.
