Language in Jaipur, Dutch! (4)
I believe the answer is:
urdu
'language' is the definition.
(Urdu is an example)
'in jaipur dutch' is the wordplay.
'in' says the answer is hidden in the clue.
'URDU' is hidden within 'jaipur dutch'.
(Other definitions for urdu that I've seen before include "Language spoken by Moslems in Pakistan and India" , "Sanskrit language" , "Language closely related to Hindi" , "Language used in Pakistan, India" , "Sub-continental language" .)
