Problems involving empty tenements outside capital of Belarus (8)
I believe the answer is:
troubles
'problems' is the definition.
('trouble' can be a synonym of 'problem')
'empty tenements outside capital of belarus' is the wordplay.
'empty' says to hollow out the word (remove centre letters).
'outside' is an insertion indicator (some letters go outside others).
'capital of belarus' becomes 'rouble' (I can't explain this - if you can you should believe this answer much more).
'tenements' with its centre taken out is 'ts'.
'ts' enclosing 'rouble' is 'TROUBLES'.
'involving' is the link.
Can you help me to learn more?
(Other definitions for troubles that I've seen before include "Inconveniences, perturbs" , "Old song: 'Pack up your . . . . . . . . In your old kit bag'" , "Problems and difficulties - subtle or what?" , "Difficulties, worries" , "Distressing or painful events" .)
