American stalls in Quebec during break (7)
I believe the answer is:
parquet
'american stalls' is the definition.
(US term for theatre stalls)
'quebec during break' is the wordplay.
'quebec' becomes 'que' (abbreviation for Quebec).
'during' indicates putting letters inside.
'break' becomes 'part'.
'que' placed inside 'part' is 'PARQUET'.
'in' is the link.
(Other definitions for parquet that I've seen before include "Blocks of wood" , "Floor-covering of wooden blocks" , "Hardwood floor covering" , "that may cover floor" , "Type of wooden flooring" .)
