Prison more stylish? (6)
I believe the answer is:
cooler
'prison' is the definition.
(informal term for a prison)
'more stylish?' is the wordplay.
I cannot really see how this works, but
'stylish?' could be 'cool' and 'cool' is found within the answer.
The remaining letters 'er' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cooler that I've seen before include "less enthusiastic" , "Fan" , "more sophisticated" , "Nick" , "It's not so hot" .)
