Make progress with a drink about (4)
I believe the answer is:
gain
'make progress' is the definition.
(I've seen this in another clue)
'a drink about' is the wordplay.
'drink' becomes 'gin' (gin is a kind of drink).
'about' indicates putting letters inside.
'a' put within 'gin' is 'GAIN'.
'with' is the link.
(Other definitions for gain that I've seen before include "Obtain to one's advantage" , "Obtain, secure" , "Earn, profit" , "Benefit; put on (weight)" , "Pick up" .)
