Month right in capital city of Russia (8)
I believe the answer is:
novgorod
'month right in capital city of russia' is the definition.
I can't judge whether this defines the answer.
'month right in capital city of russia' is the wordplay.
'month' becomes 'Nov' (abbreviation for November).
'right' becomes 'r' (common abbreviation).
'in' is an insertion indicator.
'capital city of russia' becomes 'good' (I can't justify this - if you can you should believe this answer much more).
'r' inserted into 'good' is 'gorod'.
'nov'+'gorod'='NOVGOROD'
Can you help me to learn more?
(Another definition for novgorod that I've seen is " Russian city".)
