Company running airports here purchases church and country house (5)
I believe the answer is:
dacha
'country house' is the definition.
(dacha is a kind of country house)
'company running airports here purchases church' is the wordplay.
I cannot really see how this works, but
'church' could be 'ch' (abbreviation on maps etc) and 'ch' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for dacha that I've seen before include "Country home in Russia" , "Russian dwelling" , "Russian country home" , "Second home in the country for Muscovites?" , "property overseas" .)
