Fruit drink primarily avoided after cold (6)
I believe the answer is:
cherry
'fruit' is the definition.
(cherry is a kind of fruit)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for cherry that I've seen before include "Cerise" , ""Loveliest of trees, the ____ now" (Housman)" , "Red fruit with a single hard stone" , "'Tree, fruit and colour (6)'" , "Tree with stoned fruit" .)
