Break a hole in a wall (6)
I believe the answer is:
recess
I believe this clue is a double definition.
'break' is the first definition.
(I know that break can be written as recess)
'a hole in a wall' is the second definition.
(term for a set back part of a wall)
(Other definitions for recess that I've seen before include "take time out" , "Suspension of a session for a rest" , "Secluded place" , "Enclosure set back or indented" , "Space set back in wall" .)
