Without Karnataka’s IT & Communication scheme (8)
I believe the answer is:
sanskrit
'communication scheme' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'without karnataka's it' is the wordplay.
'without' becomes 'sans' (I've seen this before).
'karnataka' becomes 'kr' (I can't explain this - if you can you should give a lot more credence to this answer).
'sans'+'kr'+'it'='SANSKRIT'
Can you help me to learn more?
(Other definitions for sanskrit that I've seen before include "Ancient Indo-European language" , "Ancient language of Hindus in India" , "Ancient Indian language" , "Ancient Hindu tongue" , "Ancient official language of India" .)
