Brush in bachelor accommodation (5)
I believe the answer is:
broom
'brush' is the definition.
(I've seen this before)
'bachelor accommodation' is the wordplay.
'bachelor' becomes 'b' (abbreviation e.g. BA=Bachelor of Arts).
'accommodation' becomes 'room' (I have seen 'basic accommodation' mean 'room' so perhaps 'accommodation' could also mean 'room').
'b'+'room'='BROOM'
'in' acts as a link.
(Other definitions for broom that I've seen before include "Plant - sweeper" , "Sweeper (said twice for a car!)" , "cleaner" , "Yellow-flowered shrub" , "Shrub and cleaning implement" .)
