Sweeper catches newspaper boss in rest area (7)
I believe the answer is:
bedroom
'rest area' is the definition.
(I've seen this in another clue)
'sweeper catches newspaper boss' is the wordplay.
'sweeper' becomes 'broom' (a broom sweeps things up).
'catches' means one lot of letters goes inside another.
'newspaper boss' becomes 'ed' (short for editor).
'broom' going around 'ed' is 'BEDROOM'.
'in' is the link.
(Other definitions for bedroom that I've seen before include "Boudoir" , "Sleeping place" , "Space for sleeping" , "Dormitory" , "Chamber of repose" .)
