In this way, defeat perverted type (5)
I believe the answer is:
sicko
'perverted type' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'in this way defeat' is the wordplay.
'in this way' becomes 'sic' (I've seen this before).
'defeat' becomes 'ko' (I can't explain this - if you can you should give a lot more credence to this answer).
'sic'+'ko'='SICKO'
Can you help me to learn more?
(Other definitions for sicko that I've seen before include "pervert" , "Unpleasant character" , "macabre" .)
