Left food out, and 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 into 'food' is 'FLOOD'.
'and' acts as a link.
(Other definitions for flood that I've seen before include "Light" , "Brim over" , "Overflow of water" , "lot of water" , "Deluge" .)
