Vendetta draining resistance from psychoanalyst (4)
I believe the answer is:
feud
'vendetta' is the definition.
(I've seen this in another clue)
'resistance from psychoanalyst' is the wordplay.
'resistance' becomes 'r' (electronics abbreviation).
'from' indicates named letters should be taken away.
'psychoanalyst' becomes 'freud' (Sigmund Freud, father of psychoanalysis).
'freud' with 'r' taken away is 'FEUD'.
'draining' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for feud that I've seen before include "Quarrel; spat" , "quarrel without end" , "Conflict" , "Sustained enmity" , "Piece of land once" .)
