Any salt forced to shrink (7)
I believe the answer is:
analyst
'shrink' is the definition.
(I've seen this before)
'any salt forced' is the wordplay.
'forced' is an anagram indicator.
'any'+'salt'='anysalt'
'anysalt' with letters rearranged gives 'ANALYST'.
'to' is the link.
(Other definitions for analyst that I've seen before include "Examiner - psychiatrist" , "Chemical researcher" , "Psychological therapist" , "Expert who studies data and recommends appropriate action" , "Freud was one" .)
