Relief as revolutionary secures victory, help arriving at critical moment?
I believe the answer is:
life-saver
'help arriving at critical moment?' is the definition.
I can't tell whether this defines the answer.
'relief as revolutionary secures victory' is the wordplay.
'revolutionary' indicates an anagram.
'secures' indicates putting letters inside.
'victory' becomes 'v'.
'relief'+'as'='reliefas'
'reliefas' with letters rearranged gives 'lifesaer'.
'lifesaer' enclosing 'v' is 'LIFE-SAVER'.
Can you help me to learn more?
(Other definitions for life-saver that I've seen before include "Vital help when in serious difficulty" , "One rescuing swimmer" , "I've flares for person who helps in time of great need" , "Something that comes to one's aid at a critical moment" .)
