Fruit in a Newton (3)
I believe the answer is:
fig
'fruit in a newton' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for fig that I've seen before include "This tree's leaf may cover nudity" , "Soft pear-shaped fruit" , "Sweet fleshy fruit, often dried" , "Fruit with lots of seeds" , "This leaf may conceal nudity in art" .)
