Set subsequently including father has to fail (2,4,3,3)
I believe the answer is:
go down the pan
'to fail' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'set subsequently including father' is the wordplay.
'set' becomes 'godown' (set can mean to sink or go down).
'subsequently' becomes 'then' (synonyms).
'including' indicates putting letters inside.
'father' becomes 'pa' (pa can mean dad or father).
'then' going around 'pa' is 'thepan'.
'godown'+'thepan'='GO DOWN THE PAN'
'has' is the link.
Can you help me to learn more?
(Other definitions for go down the pan that I've seen before include "deteriorate rapidly" , "Fail utterly" .)
