Career in orchestra decided (5)
I believe the answer is:
trade
'career' is the definition.
(thesaurus)
'in orchestra decided' is the wordplay.
'in' indicates a hidden word.
'TRADE' is hidden in the letters of 'orchestra decided'.
(Other definitions for trade that I've seen before include "Give and receive (blows)" , "Commercial exchange of goods and services" , "Buying/selling of goods" , "Transaction" , "A skilled craft to earn living" .)
