Left food out, and ample water (5)

Ross

I believe the answer is:

flood

I'm a little stuck... Click here to teach me more about this clue!

'ample water' is the definition.
'flood' can be an answer for 'water' (I've seen this before). I am unsure of the 'ample' bit.

'left food out' is the wordplay.
'left' becomes 'L' (common abbreviation).
'out' indicates putting letters inside.
'l' put inside 'food' is 'FLOOD'.

'and' is the link.

Can you help me to learn more?

(Other definitions for flood that I've seen before include "Light" , "Overwhelming amount" , "Brim over" , "Oversupply" , "lot of water" .)
