Shrink from yacht, spirits dashed (12)
I believe the answer is:
psychiatrist
'shrink' is the definition.
(synonyms)
'yacht spirits dashed' is the wordplay.
'dashed' indicates anagramming the letters.
'yacht'+'spirits'='yachtspirits'
'yachtspirits' is an anagram of 'PSYCHIATRIST'.
'from' acts as a link.
(Other definitions for psychiatrist that I've seen before include "Treater of mental illness" , "Mental-illness doctor" , "Shrink" , "Treater of mental disorders" , "Carl Jung, perhaps" .)
