Search for something in the baroque style (5)
I believe the answer is:
quest
'search for' is the definition.
(thesaurus)
'something in the baroque style' is the wordplay.
'something' indicates a hidden word (I've seen this in other clues).
'QUEST' can be found hidden inside 'in baroque style'.
(Other definitions for quest that I've seen before include "Mission" , "Long or arduous search" , "Pursuit" , "Prolonged search" , "A search or hunt" .)
