'ingenuity' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'rooney's wife resolved anger with a vardy with no end' is the wordplay.
'rooney's wife' becomes 'a' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'resolved' indicates anagramming the letters.
'with' says to put letters next to each other.
'with no end' means to remove the last letter.
'vardy' with its final letter taken off is 'vard'.
'anger' after 'vard' is 'vardanger'.
'vardanger' is an anagram of 'vagardner'.
'a'+'vagardner'='AVA GARDNER'

'of' is the link.
