Some chocolates or toffees? Not exactly (4,2)
I believe the answer is:
sort of
'not exactly' is the definition.
(I've seen this before)
'some chocolates or toffees?' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'SORT OF' can be found hidden inside 'chocolates or toffees'.
(Other definitions for sort of that I've seen before include "To some (great or small) extent" , "Not quite, but almost" , "Somewhat" , "Not exactly" , "Possibly, to an extent" .)
