Cooler tenants? (9)
I believe the answer is:
prisoners
'cooler tenants?' is the definition.
(people resident in a prison or cooler)
'cooler tenants?' is the wordplay.
'cooler' becomes 'prison' (cooler can informally mean a prison).
'tenants?' becomes 'ers' (I can't explain this - if you can you should believe this answer much more).
'prison'+'ers'='PRISONERS'
Can you help me to learn more?
(Other definitions for prisoners that I've seen before include "People in jail or captives" , "Detainees" , "cons" , "Convicts, inmates" , "Captives or convicts" .)
