Trophy held by acupuncturist (3)
I believe the answer is:
cup
'trophy' is the definition.
(cup is a kind of trophy)
'held by acupuncturist' is the wordplay.
'held by' indicates the answer is hidden within the clue.
'CUP' can be found hidden inside 'acupuncturist'.
(Other definitions for cup that I've seen before include "Chalice; trophy" , "Beaker" , "Sort of cake" , "competition" , "McCarthy, Walker or Maguire" .)
