Covers difficulties consuming Left (6)
I believe the answer is:
blinds
'covers' is the definition.
(blind is a kind of cover)
'difficulties consuming left' is the wordplay.
'difficulties' becomes 'binds' (bind is a kind of difficulty**).
'consuming' means one lot of letters goes inside another.
'left' becomes 'l' (common abbreviation).
'binds' going around 'l' is 'BLINDS'.
(Other definitions for blinds that I've seen before include "sun-block?" , "Destroys sight of window covers" , "Window covers to hinder sight" .)
