Lozenge (8)
I believe the answer is:
pastille
'lozenge' is the definition.
(I know that pastille is a type of lozenge)
This is the entire clue.
(Other definitions for pastille that I've seen before include "Small sweet/lozenge" , "Small, often medicated, sweet" , "List plea for the small sweet" , "Flavoured sweet for sucking" , "something for a sore throat" .)
