Can go berserk with opposite number at street party, maybe (8)
I believe the answer is:
carnival
'party maybe' is the definition.
'Carnival' can be an answer for 'party' (thesaurus). I am not certain of the 'maybe' bit.
'can go berserk with opposite number at street' is the wordplay.
I cannot quite understand how this works, but
'number' could be 'iv' (IV is an example) and 'iv' is found in the answer.
The remaining letters 'carnal' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for carnival that I've seen before include "Festive fair" , "Travelling funfair" , "Notting Hill event" , "festive occasion" , "Period of public revelry" .)
