Hypnotherapy target (6)
I believe the answer is:
phobia
'hypnotherapy target' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for phobia that I've seen before include "Overpowering fear" , "A lasting abnormal fear of something" , "An irrational fear or dislike" , "Obsessive and persistent fear of something" , "Irrational fear (of thing)" .)
