Small illustration of fruit (3)
I believe the answer is:
fig
I believe this is a double definition.
'small illustration' is the first definition.
(abbreviation for figure)
'fruit' is the second definition.
(fig is a kind of fruit)
'of' is the link.
(Other definitions for fig that I've seen before include "This tree's leaf may cover nudity" , "Fruit with lots of seeds" , "This leaf may conceal nudity in art" , "Soft sweet fruit of broad-leaved tree" , "Fruit full of tiny seeds" .)
