Ban flipping setter then take over (7)
I believe the answer is:
embargo
'ban' is the definition.
(I've seen this before)
'flipping setter then take over' is the wordplay.
'flipping setter' becomes 'embar' (I am not sure about this - if you are sure you should believe this answer much more).
'then' becomes 'ergo' (therefore).
'take' is a deletion indicator.
'over' becomes 're'.
'ergo' with 're' taken away is 'go'.
'embar'+'go'='EMBARGO'
Can you help me to learn more?
(Other definitions for embargo that I've seen before include "Commercial break" , "Prohibit" , "Order forbidding ships to enter or leave port, and a ban on trade" , "Government order imposing a trade barrier" , "Commercial ban" .)
