Have nothing to do with row about pig (6)
I believe the answer is:
disown
'have' is the definition.
(I know that disown is a more specific form of the action deprive)
'row about pig' is the wordplay.
'row' becomes 'din' (both can mean a loud disturbance).
'about' indicates putting letters inside.
'pig' becomes 'sow' (I've seen this in another clue).
'din' enclosing 'sow' is 'DISOWN'.
'nothing to do with' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for disown that I've seen before include "Refuse responsibility for" , "Reject all connection or relationship with" , "Repudiate, disclaim" , "Repudiate - disinherit" , "Disclaim or deny" .)
