Moving day in a country house (5)
I believe the answer is:
dacha
This clue might be a double definition.
'moving day' is the first definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'country house' is the second definition.
(dacha is a kind of country house)
'in a' is the link.
Can you help me to learn more?
(Other definitions for dacha that I've seen before include "summer house" , "Russian second home" , "Russian house in the country" , "property overseas" , "Russian villa" .)
