Dad holding a high card can solve all problems (7)
I believe the answer is:
panacea
'solve all problems' is the definition.
I can't tell whether this definition defines the answer.
'dad holding a high card' is the wordplay.
'dad' becomes 'pa' (both can mean one's father).
'holding' indicates putting letters inside.
'a' becomes 'an'.
'high card' becomes 'ace' (I've seen this before).
'an'+'ace'='anace'
'pa' placed around 'anace' is 'PANACEA'.
'can' acts as a link.
Can you help me to learn more?
(Other definitions for panacea that I've seen before include "Universal cure" , "that will cure anything" , "Nostrum" , "sovereign remedy" , "that's going to help a lot" .)
