Standing up, present endless fruit (3)
I believe the answer is:
fig
'standing up present endless fruit' is the definition.
'fig' can be an answer for 'fruit' (fig is a kind of fruit). I am not sure about the 'standing up present endless' bit.
'endless fruit' is the wordplay.
'endless' means to remove the last letter.
'fruit' becomes 'figs' (I've seen this before).
'figs' with its last letter taken away is 'FIG'.
Can you help me to learn more?
(Other definitions for fig that I've seen before include "Seed-packed fruit" , "Fruit with many seeds" , "This leaf may conceal nudity in art" , "Tree whose leaf may conceal nudity" , "Soft sweet fruit of broad-leaved tree" .)
