Humiliated criminal agreed to go in two days (8)
I believe the answer is:
degraded
'humiliated' is the definition.
(degrading is a kind of humiliating)
'criminal agreed to go in two days' is the wordplay.
'criminal' indicates an anagram.
'to go in' indicates putting letters inside.
'two' says to double the letters.
'days' becomes 'd'.
'agreed' is an anagram of 'egrade'.
'd' doubled is 'dd'.
'egrade' put inside 'dd' is 'DEGRADED'.
(Other definitions for degraded that I've seen before include "Lowered in quality" , "Demeaned; broken down" , "Humiliated" , "Sordid" , "Debased" .)
