I want to know the answer to the following question:
Besides the language of Kannada, what other old language was used during the western Chalukya dynasty?
All the background I'm provided with is that "During this period the other major ruling families of the Deccan, the Hoysalas, the Seuna Yadavas of Devagiri, the Kakatiya dynasty and the Southern Kalachuri, were subordinates of the Western Chalukyas and gained their independence only when the power of the Chalukya waned during the later half of the 12th century.". Is that enough to answer the question?
Answer: no
