Prisoner admitting umpteen crimes initially, evil chap (7)
I believe the answer is:
lucifer
'evil chap' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'prisoner admitting umpteen crimes initially' is the wordplay.
'prisoner' becomes 'lifer' (prisoner serving a life sentence).
'admitting' indicates putting letters inside (admit can mean to welcome in or accept).
'initially' indicates taking the first letters.
The first letters of 'umpteen crimes' is 'uc'.
'lifer' going around 'uc' is 'LUCIFER'.
Can you help me to learn more?
(Other definitions for lucifer that I've seen before include "from the abyss?" , "once a match for > Dickens" , "Rebellious angel; a match" , "flares up when struck" , "Devil - match!" .)
