Father's due back from the psychoanalyst (5)
I believe the answer is:
freud
'the psychoanalyst' is the definition.
(Sigmund Freud, father of psychoanalysis)
'father's due back' is the wordplay.
'father' becomes 'fr' (abbreviation as in a priest's title).
'back' is a reversal indicator.
'due' back-to-front is 'eud'.
'fr'+'eud'='FREUD'
'from' is the link.
(Other definitions for freud that I've seen before include "See 4" , "Painter" , "One introducing ID" , "See 8" , "See 17" .)
