Alternative given in hypnotherapy (5)
I believe the answer is:
other
'alternative' is the definition.
(I've seen this before)
'in hypnotherapy' is the wordplay.
'in' says the answer is hidden in the clue.
'OTHER' is hidden in the letters of 'hypnotherapy'.
'given' acts as a link.
(Other definitions for other that I've seen before include "Different, disparate" , "Alternate; additional" , "Different; additional" , "Remaining" , "Different, alternative" .)
