Back in Normandy: a Hungarian composer (5)
I believe the answer is:
haydn
'composer' is the definition.
(Haydn is an example)
'back in normandy a hungarian' is the wordplay.
'back' is a reversal indicator.
'in' indicates a hidden word.
'ndyah' is hidden in the letters of 'normandy a hungarian'.
'ndyah' in reverse letter order is 'HAYDN'.
(Other definitions for haydn that I've seen before include "Austrian symphonist, d. 1809" , "Austrian musician" , "Joseph -, Austr. composer (Farewell Symphony)" , "Josef --, prolific composer" , "Joseph -, prolific eighteenth to nineteenth century Austrian composer" .)
