Stop and drink (6)
I believe the answer is:
scotch
I believe this clue is a double definition.
'stop' is the first definition.
(I've seen this before)
'drink' is the second definition.
(Scotch is an example)
'and' acts as a link.
(Other definitions for scotch that I've seen before include "Northern whisky" , "providing nursery facility in school" , "Whisky (not whiskey!)" , "A short" , "Type of egg" .)
