Cured about first person to have passed away (8)
I believe the answer is:
remedied
'cured about first person to have passed away' is the definition.
I can't tell whether this defines the answer.
'about first person to have passed away' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'first person' becomes 'me' (first-person pronoun).
'to have' is a charade indicator (letters next to each other).
'passed away' becomes 'died' ('die' can be a synonym of 'pass away').
're'+'me'+'died'='REMEDIED'
Can you help me to learn more?
(Other definitions for remedied that I've seen before include "Put right" , "sorted out" .)
