Inject new life into right sort of rest cure (9)
I believe the answer is:
resurrect
'inject new life' is the definition.
I can't tell whether this defines the answer.
'right sort of rest cure' is the wordplay.
'right' becomes 'r' (common abbreviation).
'sort of' is an anagram indicator.
'rest'+'cure'='restcure'
'restcure' anagrammed gives 'esurrect'.
'r'+'esurrect'='RESURRECT'
'into' is the link.
Can you help me to learn more?
(Other definitions for resurrect that I've seen before include "Revive (something)" , "Bring back to life" , "Revive; disinter" , "Restore to life" , "Cause to become alive again" .)
