Draw back from room (4)
I believe the answer is:
ward
'room' is the definition.
(I've seen this before)
'draw back' is the wordplay.
'back' says the letters should be written in reverse.
'draw' in reverse letter order is 'WARD'.
'from' acts as a link.
(Other definitions for ward that I've seen before include "custody" , "zone for votes" , "Electoral district; Mrs Humphry ---" , "Separate room" , "Hospital room; part of borough" .)
