Figurative foe changed heart after total bighead arrived (11)
I believe the answer is:
allegorical
'figurative' is the definition.
(I've seen this before)
'foe changed heart after total bighead arrived' is the wordplay.
I cannot really see how this works, but
'total' could be 'all' (I've seen this in another clue) and 'all' is found in the answer.
'bighead' could be 'ego' (I've seen this in another clue) and 'ego' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for allegorical that I've seen before include "is fabulous" , "Containing a hidden meaning" , "depicted in fable" , "In parabolic" , "symbolic" .)
