Utterly disorganised prince turning back on elegance (8)
I believe the answer is:
anarchic
'utterly disorganised' is the definition.
'anarchic' can be an answer for 'disorganised' (I've seen this before). I am not certain of the 'utterly' bit.
'prince turning back on elegance' is the wordplay.
'prince' becomes 'rana' (I can't explain this - if you can you should believe this answer much more).
'turning back' says the letters should be written backwards.
'on' is a charade indicator (letters next to each other).
'elegance' becomes 'chic' (chic is a kind of elegance).
'rana' backwards is 'anar'.
'anar'+'chic'='ANARCHIC'
Can you help me to learn more?
(Other definitions for anarchic that I've seen before include "Without law or control" , "Lawless, lacking government or control" , "Disorderly" , "Lawless, out of control behaviour" , "ignoring the law" .)
