A lawyer unchaste characters house (5)
I believe the answer is:
dacha
'house' is the definition.
(I know that dacha is a type of house)
'a lawyer unchaste characters' is the wordplay.
'a lawyer' becomes 'da' (abbreviation for District Attorney).
'unchaste characters' becomes 'cha' (I can't explain this - if you can you should give a lot more credence to this answer).
'da'+'cha'='DACHA'
Can you help me to learn more?
(Other definitions for dacha that I've seen before include "Russian holiday cottage" , "Russian's second home in the country" , "Second home in the country for Muscovites?" , "Russian retreat" , "Russian villa" .)
