Father’s holding a winning card, which makes all well (7)
I believe the answer is:
panacea
'all well' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'father's holding a winning card' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'holding' is an insertion indicator.
'a' becomes 'an'.
'winning card' becomes 'ace' (I've seen this before).
'an'+'ace'='anace'
'pa' placed around 'anace' is 'PANACEA'.
'which makes' is the link.
Can you help me to learn more?
(Other definitions for panacea that I've seen before include "Panpharmacon" , "comprehensive fix" , "fixes all complaints" , "universal solution" , "Cure for all things" .)
