Real logic dealt badly with hidden meaning (9)
I believe the answer is:
allegoric
'with hidden meaning' is the definition.
(an allegory is a hidden meaning)
'real logic dealt badly' is the wordplay.
'dealt badly' indicates an anagram.
'real'+'logic'='reallogic'
'reallogic' with letters rearranged gives 'ALLEGORIC'.
(Other definitions for allegoric that I've seen before include "with symbolic meaning" , "Figurative" , "serving as symbol" .)
