Language without appeal draws in two kings (8)
I believe the answer is:
sanskrit
'language' is the definition.
(Sanskrit is an example)
'without appeal draws in two kings' is the wordplay.
I cannot quite understand how this works, but
'without' could be 'sans' (I've seen this before) and 'sans' is found in the answer.
'appeal' could be 'it' and 'it' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for sanskrit that I've seen before include "Ancient Hindu tongue" , "Ancient language of Hindus in India" , "Ancient Indian language" , "Ancient Indo-European language" , "Ancient official language of India" .)
