Aliment (7)
I believe the answer is:
nourish
'aliment' is the definition.
(I know that aliment can be written as nourish)
This is all the clue.
(Other definitions for nourish that I've seen before include "Keep alive and well with food" , "Supply with food, keep well" , "support" , "Foster or cherish, often with food" , "Nurture, sustain" .)
