The one rule broken in rigged vote (4,4)
I believe the answer is:
true love
'the one' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'rule broken in rigged vote' is the wordplay.
'broken' indicates anagramming the letters.
'in' indicates putting letters inside.
'rigged' indicates anagramming the letters.
'rule' is an anagram of 'ruel'.
'vote' is an anagram of 'tove'.
'ruel' put inside 'tove' is 'TRUE-LOVE'.
Can you help me to learn more?
(Another definition for true love that I've seen is " Genuine affection?".)
