Nurse the man who lost his head and broke a leg (5)
I believe the answer is:
angel
This clue might be a double definition.
'nurse' is the first definition.
(collins dictionary)
'the man who lost his head and broke a leg' is the second definition.
'Angel' can be an answer for 'the man'. I'm not sure about the rest of the definition.
Can you help me to learn more?
(Other definitions for angel that I've seen before include "Theatrical backer" , "Obliging person" , "Sponsor" , "Heavenely messenger" , "Holy being" .)
