Fruit Noel brought back about the sixth of September
I believe the answer is:
lemon
'fruit' is the definition.
(lemon is a kind of fruit)
'noel brought back about the sixth of september' is the wordplay.
'brought back' says the letters should be written in reverse.
'about' means one lot of letters goes inside another.
'the sixth of september' becomes 'm' (6th letter of 'september').
'noel' written backwards gives 'leon'.
'leon' placed around 'm' is 'LEMON'.
(Other definitions for lemon that I've seen before include "Yellow fruit (it's also the answer!)" , "very different from peach?" , "Fruit-tree" , "Melon (anag)" , "Citrus fruit (is it the answer?)" .)
