Send what is right to issue (5)
I believe the answer is:
remit
'send' is the definition.
(I've seen this in another clue)
'right to issue' is the wordplay.
'right' becomes 'r' (common abbreviation).
'to issue' becomes 'emit' (both can mean to give out or radiate).
'r'+'emit'='REMIT'
'what is' acts as a link.
(Other definitions for remit that I've seen before include "Send; abate; cancel" , "send money, maybe" , "Area(s) of responsibility or to be dealt with" , "Pardon (a sin)" , "Desist from" .)
