Symbolic tales spreading lies galore (10)
I believe the answer is:
Here is my best explanation:
'symbolic tales' is the definition.
'allegories' can be an answer for 'tales'. I also know that 'symbolic' relates to this answer.
'spreading lies galore' is the wordplay.
'spreading' indicates an anagram.
'liesgalore' anagrammed gives 'ALLEGORIES'.
(Another definition for allegories that I've seen is "Symbolic narratives".)
