Utter madness back in Kiev area (4)
I believe the answer is:
rave
'utter madness' is the definition.
'rave' can be an answer for 'utter' (raving is a kind of uttering). I'm unsure of the 'madness' bit.
'back in kiev area' is the wordplay.
'back' is a reversal indicator.
'in' indicates a hidden word.
'evar' is hidden in the letters of 'kiev area'.
'evar' reversed gives 'RAVE'.
Can you help me to learn more?
(Other definitions for rave that I've seen before include "Fume" , "Wild party; go mad" , "modern dance music" , "Rant about an all-night dance party?" , "Talk wildly and irrationally" .)
