1, for example, left with small bill (9)
I believe the answer is:
landscape
'1 for example' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'left with small bill' is the wordplay.
'left' becomes 'l' (common abbreviation).
'with' becomes 'and'.
'small' becomes 's' (abbreviation - e.g. clothes size).
'bill' becomes 'cape' (both can mean a promontory).
'l'+'and'+'s'+'cape'='LANDSCAPE'
(Other definitions for landscape that I've seen before include "Oil perhaps" , "Type of painting" , "Expanse of scenery" , "scene" , "Artistic work" .)
