Left food out with water (5)
I believe the answer is:
flood
'water' is the definition.
(I've seen this before)
'left food out' is the wordplay.
'left' becomes 'l' (common abbreviation).
'out' indicates putting letters inside.
'l' put inside 'food' is 'FLOOD'.
'with' is the link.
(Other definitions for flood that I've seen before include "Overflow of water" , "lot of water" , "Brim over" , "Oversupply" , "Inundation" .)
