Approve, sanction (7)
I believe this is a double definition.
'approve' is the first definition.
(I've seen this before)
'sanction' is the second definition.
(I've seen this in another clue)
(Other definitions for ratify that I've seen before include "Give formal approval to" , "Authorise" , "Authenticate" , "OK" , "Sign or give formal consent" .)
