Resuscitate (6)
I believe the answer is:
revive
'resuscitate' is the definition.
(I know that resuscitate can be written as revive)
This is all the clue.
(Other definitions for revive that I've seen before include "Restore to life or consciousness" , "bring round" , "(Cause to) get new life" , "Rally" , "Resuscitate" .)
