Drinking, right, but remaining vigilant (2,3,5)
I believe the answer is:
on the alert
'vigilant' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for on the alert that I've seen before include "vigilant" , "Looking out" .)
I've seen this clue in The Guardian.
Want a hint initially instead of a full solution?
