Psychoanalyst has no right to take part in family dispute (4)
I believe the answer is:
feud
'part in family dispute' is the definition.
'feud' can be an answer for 'dispute' (I've seen this before). I am not certain of the 'part in family' bit.
'psychoanalyst has no right' is the wordplay.
'psychoanalyst' becomes 'freud' (I've seen this before).
'has no' suggests deleting specific letters.
'right' becomes 'r' (common abbreviation).
'freud' with 'r' taken out is 'FEUD'.
'to take' acts as a link.
Can you help me to learn more?
(Other definitions for feud that I've seen before include "Prolonged dispute" , "Squabble" , "Long-running dispute" , "quarrel without end" , "Bitter quarrel between two parties" .)
