Stein-like beer mug (7)
I believe the answer is:
tankard
I believe this clue is a double definition.
'stein' is the first definition.
(I've seen this in another clue)
'beer mug' is the second definition.
(I've seen this before)
'like' acts as a link.
(Other definitions for tankard that I've seen before include "Beer glass" , "One-handled drinking mug" , "Drinking vessel with a handle" , "Large drinking vessel" , "A drinking mug with handle" .)
