Satirical comedian, one taking on rise in crime during corruption (7)
I believe the answer is:
ironist
'satirical comedian' is the definition.
'ironist' can be an answer for 'comedian' (thesaurus). I'm not certain of the 'satirical' bit.
'one taking on rise in crime during corruption' is the wordplay.
'one' becomes 'i' (Roman numeral).
'taking on' says to put letters next to each other.
'rise in crime' becomes 'nis' (I can't justify this - if you can you should give a lot more credence to this answer).
'during' indicates putting letters inside.
'corruption' becomes 'rot' (rot can mean corruption or decay).
'nis' put inside 'rot' is 'ronist'.
'i'+'ronist'='IRONIST'
Can you help me to learn more?
(Other definitions for ironist that I've seen before include "Swift, for one" , "Mark Antony when making speech" , "A contrary speaker" , "One using a form of satire" , "Quasi-satirical humorist" .)
