Portly, or porter (5)
I believe the answer is:
stout
I believe this is a double definition.
'portly' is the first definition.
(I know that portly can be written as stout)
'porter' is the second definition.
(porter can mean stout)
(Other definitions for stout that I've seen before include "pint" , "drinks?" , "Overweight; porter" , "Full-bodied" , "Portly - type of dark beer" .)
