Cursed the Spanish embargo with bananas getting turned back (8)
I believe the answer is:
damnable
'cursed' is the definition.
(similar in meaning)
'the spanish embargo with bananas getting turned back' is the wordplay.
'the spanish' becomes 'el' ('the' in Spanish).
'embargo with' becomes 'ban' (a ban on trade. I am not sure about the 'with' bit.).
'bananas' becomes 'mad' (slang for insane).
'getting' means one lot of letters go next to another.
'turned back' says the letters should be written backwards.
'el'+'ban'+'mad'='elbanmad'
'elbanmad' in reverse letter order is 'DAMNABLE'.
Can you help me to learn more?
(Other definitions for damnable that I've seen before include "Pernicious" , "Awful" , "Atrocious, infernal" , "really bad" , "Execrable" .)
