Attendant on Dionysus (6)
I believe the answer is:
maenad
'attendant on dionysus' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for maenad that I've seen before include "Bacchante" , "Da, name the female follower of Bacchus." , "Woman possessed" , "A raging woman, once a follower or Dionysus" , "Frenzied or distraught woman" .)
