Cherish new wallet when penniless? (5)
I believe the answer is:
nurse
'cherish' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for nurse that I've seen before include "Professional carer" , "Hospital employee" , "Tend to patient" , "Hospital tender" , "Look after the sick" .)
