Regret being incarcerated again? (6)
I believe the answer is:
repent
'regret' is the definition.
(I know that regret can be written as repent)
'being incarcerated again?' is the wordplay.
'being' becomes 'rep' (rep is a kind of being).
'incarcerated again?' becomes 'ent' (I can't explain this - if you can you should believe this answer much more).
'rep'+'ent'='REPENT'
Can you help me to learn more?
(Other definitions for repent that I've seen before include "Be contrite, ye sinners" , "Express remorse for sin" , "creeping along the ground" , "Feel regret/remorse" , "Be ashamed" .)
