Breaking rule with date, right? I am (9)
I believe the answer is:
adulterer
'i am' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'breaking rule with date right?' is the wordplay.
'breaking' is an anagram indicator.
'with' is a charade indicator (letters next to each other).
'right?' becomes 'R' (common abbreviation).
'rule' after 'date' is 'daterule'.
'daterule' anagrammed gives 'adultere'.
'adultere'+'r'='ADULTERER'
(Other definitions for adulterer that I've seen before include "Man United playing away" , "one known to cheat" , "Sinner" , "Durer tale (anag)" , "Away player" .)
