Expressing sincere gratitude is important in any language. If you want to say "Thank you heartily" in Kannada, a fitting translation would be "ತುಂಬಾ ಧನ್ಯವಾದಗಳು" (tumba dhanyavaadagalu). This phrase conveys a deep sense of appreciation and is suitable for situations where you want to express more than a simple thank you. Kannada offers various ways to show gratitude, and using "ತುಂಬಾ ಧನ್ಯವಾದಗಳು" is a great way to express sincere thanks.
