Search for something in an antique style (5)
I believe the answer is:
quest
'search for' is the definition.
(thesaurus)
'something in an antique style' is the wordplay.
'something' says the answer is hidden in the clue (I've seen this in other clues).
'QUEST' is hidden in the letters of 'in antique style'.
(Other definitions for quest that I've seen before include "Pursuit" , "Prolonged search" , "Mission" , "A search or hunt" , "Hunt, goal" .)
