Dark centre in trattoria wine carrier (6)
I believe the answer is:
carafe
'wine carrier' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'dark centre in trattoria' is the wordplay.
'centre' indicates the central letters.
'in' indicates putting letters inside.
'trattoria' becomes 'cafe' (I can't justify this - if you can you should give a lot more credence to this answer).
The middle of 'dark' is 'ar'.
'ar' going into 'cafe' is 'CARAFE'.
Can you help me to learn more?
(Other definitions for carafe that I've seen before include "Wine server" , "Bottle with a stopper, for wine or water" , "Open-topped glass container" , "It may provide drink" , "Wine, water, jug" .)
