Language from party putting off both sides (5)
I believe the answer is:
hindi
'language' is the definition.
(Hindi is an example)
'from party putting off both sides' is the wordplay.
I cannot really understand how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for hindi that I've seen before include "Asian language" , "Ind. Language" , "An official language of India" , "Language of northern India" , "language many use" .)
