Flyer that talks about advanced inner personality (5)
I believe the answer is:
anima
'inner personality' is the definition.
(I've seen this before)
'flyer that talks about advanced' is the wordplay.
I cannot really understand how this works, but
'about' could be 'a' (abbreviation in Chambers) and 'a' is found within the answer.
'advanced' could be 'a' and 'a' is present in the answer.
The remaining letters 'nim' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for anima that I've seen before include "Witty remark" , "Soul" , "Inner personality (psychol.)" , "Subconscious part of the psyche" , "Showing true inner self" .)
