Idiot going round Brazil? (7)
I believe the answer is:
nutcase
'idiot' is the definition.
(both can mean a mad person)
'going round brazil?' is the wordplay.
I cannot really understand how this works, but
'brazil?' could be 'nut' (brazil is a kind of nut) and 'nut' is found within the answer.
The remaining letters 'case' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for nutcase that I've seen before include "Slang for a crazy person" , "fool" , "Crackpot" , "Cuckoo" , "Crank" .)
