Right to issue or send money (5)
I believe the answer is:
remit
'send money' 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'
'or' acts as a link.
(Other definitions for remit that I've seen before include "Send (money) in payment; pardon" , "Send < authorisation" , "Task/area assigned (to an organisation)" , "Assigned task or area" , "Abate; send (money)" .)
