Very sweet (6)
I believe the answer is:
sugary
'very sweet' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sugary that I've seen before include "Sweet, syrupy" , "Excessively sentimental" , "Sweet, perhaps too much so" , "Over-sentimental" , "Excessively sweet or saccharine" .)
