Approaches perhaps making Warren sad (5,4)
I believe the answer is:
draws near
'approaches' is the definition.
('draw near' can be a synonym of 'approach')
'making warren sad' is the wordplay.
'making' indicates anagramming the letters.
'warren'+'sad'='warrensad'
'warrensad' anagrammed gives 'DRAWS NEAR'.
'perhaps' acts as a link.
(Other definitions for draws near that I've seen before include "comes to" , "Approaches" .)
