Break alcove (6)
I believe the answer is:
recess
This clue is a double definition.
'break' is the first definition.
(recessing is a kind of breaking)
'alcove' is the second definition.
(thesaurus)
(Other definitions for recess that I've seen before include "Temporary suspension of a session" , "Break - depression" , "Niche, hollow in a wall" , "When Parliament is not sitting" , "Small set-back space" .)
