Time for a quick coffee? (7)
I believe the answer is:
instant
I believe this is a double definition.
'time' is the first definition.
(I have seen 'Short time ' mean 'instant' so perhaps 'time' could also mean 'instant')
'quick coffee?' is the second definition.
(I've seen this in another clue)
'for a' acts as a link.
(Other definitions for instant that I've seen before include "No need to cook" , "Immediate; moment in time" , "Short time; immediate" , "Jiffy" , "Trice" .)
