Old man receiving a card: get well with it (7)
I believe the answer is:
'well with it' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'old man receiving a card' is the wordplay.
'old man' becomes 'pa' (both can mean someone's father).
'receiving' indicates putting letters inside.
'a' becomes 'an'.
'card' becomes 'ace' (ace is a type of playing card).
'pa' placed around 'anace' is 'PANACEA'.
'get' is the link.
Can you help me to learn more?
(Other definitions for panacea that I've seen before include "Cure for all things" , "Remedy for all kinds of diseases or troubles" , "Solution to all difficulties" , "Cure for all ills" , "A soldier in the World War One Aus. and NZ Army Corps" .)
