Worry about a fine container for drink (6)
I believe the answer is:
carafe
'container for drink' is the definition.
I can't tell whether this defines the answer.
'worry about a fine' is the wordplay.
'worry' becomes 'care' (eg without a care means without a worry).
'about' indicates putting letters inside.
'fine' becomes 'f' (abbreviation).
'a'+'f'='af'
'care' placed around 'af' is 'CARAFE'.
Can you help me to learn more?
(Other definitions for carafe that I've seen before include "Wide-necked bottle for water or wine" , "It may provide drink" , "Open-topped container for wine or water" , "Wine, water, jug" , "in which one has wine?" .)
