Come to an arrangement in a wood after party (2,1,4)
I believe the answer is:
do a deal
'come to an arrangement' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'a wood after party' is the wordplay.
I cannot really understand how this works, but
'a' is within the answer.
'wood' could be 'deal' (deal is a kind of wood) and 'deal' is located in the answer.
'party' could be 'do' (do is a kind of party) and 'do' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for do a deal that I've seen before include "Transact" , "Reach an agreement" .)
