Europe stops bananas retaining curve, centrally? Absurd (12)
I believe the answer is:
preposterous
'absurd' is the definition.
(I know that absurd can be written as preposterous)
'europe stops bananas retaining curve centrally?' is the wordplay.
'bananas' is an anagram indicator (informal term for mad).
'retaining' indicates putting letters inside (inserted letters are held or retained).
'centrally?' says to take the centre (I've seen 'centrally' mean this).
The centre of 'curve' is 'r'.
'europe'+'stops'='europestops'
'europestops' is an anagram of 'peposterous'.
'peposterous' going around 'r' is 'PREPOSTEROUS'.
(Other definitions for preposterous that I've seen before include "Utterly absurd" , "Unreasonable - fatuous" , "Laughable" , "Ludicrous" , "Crazy" .)
