What should get one well? Old man receives a card (7)
I believe the answer is:
panacea
'what should get one well?' is the definition.
I can't tell whether this definition defines the answer.
'old man receives a card' is the wordplay.
'old man' becomes 'pa' (both can mean someone's father).
'receives' indicates putting letters inside (inserted letters are received).
'a' becomes 'an'.
'card' becomes 'ace' (ace is a type of playing card).
'an'+'ace'='anace'
'pa' going around 'anace' is 'PANACEA'.
Can you help me to learn more?
(Other definitions for panacea that I've seen before include "A soldier in the World War One Aus. and NZ Army Corps" , "fixes all complaints" , "A cure-all for diseases or troubles" , "sovereign remedy" , "Remedy for all kinds of diseases or troubles" .)
