Restore to normal life (12)
I believe the answer is:
rehabilitate
'restore to normal life' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for rehabilitate that I've seen before include "Bring back into good condition" , "Restore to normal life" , "Help someone recover their former good health" , "Restore to health" , "Restore the reputation of (someone)" .)
