Avoid getting some confectionery (5)
I believe the answer is:
fudge
I believe this clue is a double definition.
'avoid' is the first definition.
(I know that avoid is the is a more specific form of the action of fudge.)
'some confectionery' is the second definition.
(fudge is a kind of confectionery)
'getting' is the link.
(Other definitions for fudge that I've seen before include "Sweet; nonsense (arch.)" , "Something sweet" , "Falsify - soft sweet" , "Soft toffee" , "Confectionery" .)
