Sound to acquire comfortable house (8)
I believe the answer is:
dwelling
'house' is the definition.
(somewhere people live)
'sound to acquire comfortable' is the wordplay.
'sound' becomes 'ding' (I've seen this before).
'to acquire' means one lot of letters goes inside another.
'comfortable' becomes 'well' (I can't justify this - if you can you should give a lot more credence to this answer).
'ding' enclosing 'well' is 'DWELLING'.
Can you help me to learn more?
(Other definitions for dwelling that I've seen before include "Home" , "house" , "Living; abode" , "Place of residence" , "Harping" .)
