Monk getting Russian leader into trouble? (7)
I believe the answer is:
brother
'monk' is the definition.
(thesaurus)
'russian leader into trouble?' is the wordplay.
'russian leader' becomes 'r' (I am not sure about this - if you are sure you should believe this answer much more).
'into' means one lot of letters goes inside another.
'trouble?' becomes 'bother' ('bother' can be a synonym of 'trouble').
'r' going into 'bother' is 'BROTHER'.
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for brother that I've seen before include "Union member - male relative" , "Male sibling" , "Eg, monk, friar" , "Fellow-member" , "Close relative" .)
