Guarantee to get organised after conflict, with time (7)
I believe the answer is:
warrant
'guarantee' is the definition.
('warrant' can be a synonym of 'guarantee')
'organised after conflict with time' is the wordplay.
'organised' becomes 'ran' (I've seen this before).
'after' means one lot of letters go next to another.
'conflict with' becomes 'war' (war is a kind of conflict. I am not sure about the 'with' bit.**).
'time' becomes 't'.
'ran' put after 'war' is 'warran'.
'warran'+'t'='WARRANT'
'to get' is the link.
Can you help me to learn more?
(Other definitions for warrant that I've seen before include "Authorise, justify" , "Justify; authorisation" , "Merit, justify" , "Writ for arrest" , "Travel pass" .)
