Are such friends apt to be drunk? (5)
I believe the answer is:
stout
'drunk?' is the definition.
Both the answer and definition are adjectives. Maybe there's a link between them I don't understand?
'are such friends apt to' is the wordplay.
I cannot really understand how this works, but
'to' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'be' is the link.
Can you help me to learn more?
(Other definitions for stout that I've seen before include "Dark beer for the rather fat" , "Fat; dependable" , "pint" , "drinks?" , "Rather fat; determined" .)
