About leaving notes and a drink (6)
I believe the answer is:
coffee
'a drink' is the definition.
(I know that coffee is a type of drink)
'about leaving notes' is the wordplay.
'about' indicates putting letters inside.
'leaving' becomes 'off' (as in 'I'm off').
'notes' becomes 'cee' (I can't justify this - if you can you should believe this answer much more).
'off' going into 'cee' is 'COFFEE'.
'and' is the link.
Can you help me to learn more?
(Other definitions for coffee that I've seen before include "Hot beverage" , "Common drink" , "Drink from roasted beans" , "Cappuccino or espresso, say" , "Common stimulant" .)
