Issue returning for renowned healer (4)
I believe the answer is:
time
'renowned healer' is the definition.
'time' can be an answer for 'healer' ('time is the great healer'). I am unsure of the 'renowned' bit.
'issue returning' is the wordplay.
'issue' becomes 'emit' (both can mean to give out or radiate).
'returning' is a reversal indicator.
'emit' written backwards gives 'TIME'.
'for' is the link.
Can you help me to learn more?
(Other definitions for time that I've seen before include "Procrastination is the thief of ." , "Age" , "'Every ... we say goodbye, I cry a little' /Cole Porter" , "Era" , "See 15" .)
