Nothing left, I have fruit (5)
I believe the answer is:
olive
'fruit' is the definition.
(I know that olive is a type of fruit)
'nothing left i have' is the wordplay.
'nothing' becomes 'O' (looks like zero - 0).
'left' becomes 'l' (common abbreviation).
'i have' becomes 'I've' (contraction of 'I have').
'o'+'l'+'ive'='OLIVE'
(Other definitions for olive that I've seen before include "Type of green" , "It's branch is a symbol of peace" , "woman" , "Greyish-green colour" , "Stoned fruit" .)
