Comrade, drink up! (3)
I believe the answer is:
pal
This could be a double definition.
'comrade' is the first definition.
(I've seen this in other clues)
'drink up' is the second definition.
Although both the answer and definition are verbs in their base form, I cannot understand how they can define each other.
Can you help me to learn more?
(Other definitions for pal that I've seen before include "Crony" , "Friend (colloq.)" , "Mate, buddy" , "Brother" , "Bud" .)
