Frenzied woman made an error (6)
I believe the answer is:
maenad
'frenzied woman' is the definition.
(I've seen this in another clue)
'made an error' is the wordplay.
'error' indicates anagramming the letters.
'made'+'an'='madean'
'madean' is an anagram of 'MAENAD'.
(Other definitions for maenad that I've seen before include "A raging woman, once a follower or Dionysus" , "Name da for a fierce woman" , "Wild woman follower of Dionysus" , "Bacchante" , "Woman possessed" .)
