Fool taking role inwardly confused (4)
I believe the answer is:
prat
'fool' is the definition.
(I know that fool can be written as prat)
'taking role inwardly confused' is the wordplay.
'taking role' becomes 'pr' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'inwardly' indicates the central letters (only the letters inside the word are used).
'confused' becomes 'all at sea' (I've seen this in another clue).
The middle of 'allatsea' is 'at'.
'pr'+'at'='PRAT'
Can you help me to learn more?
(Other definitions for prat that I've seen before include "Rapt like silly ass" , "Rapt kind of fool" , "Incompetent idiot" , "Wally" , "In slang, a fool" .)
