Language used in skirmish in Didwana? (5)
I believe the answer is:
hindi
'language' is the definition.
(Hindi is an example)
'in skirmish in didwana?' is the wordplay.
'in' says the answer is hidden in the clue.
'HINDI' is hidden within 'skirmish in didwana'.
'used' is the link.
(Other definitions for hindi that I've seen before include "One of India's official languages" , "Indian language" , "Ind. Language" , "language many use" , "tongue" .)
