Beyond sick, ultimately crave medicated sweet (8)
I believe the answer is:
pastille
'sweet' is the definition.
(pastille is a kind of sweet)
'beyond sick ultimately crave' is the wordplay.
'beyond' becomes 'past' (to go beyond something is to go past it).
'sick' becomes 'ill' (similar in meaning).
'ultimately' indicates one should take the final letters.
The final letter of 'crave' is 'e'.
'past'+'ill'+'e'='PASTILLE'
'medicated' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for pastille that I've seen before include "Flavoured sweet for sucking" , "Lozenge, to soothe the throat perhaps" , "One medicated sweet is the alternative" , "Suck this" , "something for a sore throat" .)
