Warm drink (3,9)
I believe this is a double definition.
'warm' is the first definition.
(similar in meaning)
'drink' is the second definition.
(cordial is a kind of drink)
(Other definitions for cordial that I've seen before include "drink with a fruity flavour" , "Friendly; fruit drink" , "Warm and friendly; drink" , "Agreeable - drink" , "Pleasant - soft drink" .)
'warm drink' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for hot chocolate that I've seen before include "Bedtime drink" , "Warm drink" , "Warming drink" , "Drink with cocoa powder" , "Beverage" .)
