Right to give out pardon (5)
I believe the answer is:
remit
'pardon' is the definition.
(thesaurus)
'right to give out' is the wordplay.
'right' becomes 'r' (common abbreviation).
'to give out' becomes 'emit' ('emit' can be a synonym of 'give out').
'r'+'emit'='REMIT'
(Other definitions for remit that I've seen before include "Send - terms of reference" , "Scope of reference" , "Brief - transfer" , "Send (money) in payment; pardon" , "Transfer - area of authority" .)
