A row about a pig - say it isn't yours (6)
I believe the answer is:
disown
'say it isn't yours' is the definition.
I can't judge whether this defines the answer.
'a row about a pig' is the wordplay.
'a row' becomes 'din' (both can mean a loud disturbance).
'about' indicates putting letters inside.
'a pig' becomes 'sow' (I've seen this in another clue).
'din' placed around 'sow' is 'DISOWN'.
Can you help me to learn more?
(Other definitions for disown that I've seen before include "Refuse to be associated with (a person)" , "Refuse to be connected with" , "Cast aside" , "Disclaim or deny" , "Refuse to have anything to do with" .)
