Some have acquired a chateau as a country home (5)
I believe the answer is:
dacha
'a country home' is the definition.
'dacha' can be an answer for 'home' (I have seen 'Russian home' mean 'dacha' so perhaps 'home' could also mean 'dacha'). I am not certain of the 'a country' bit.
'some have acquired a chateau' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'DACHA' is hidden in the letters of 'have acquired a chateau'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for dacha that I've seen before include "Russian house in the country" , "summer house" , "Country home in Russia" , "Russian holiday cottage" , "Second home in the country for Muscovites?" .)
