Member with silver is able to set up drink (8)
I believe the answer is:
armagnac
'drink' is the definition.
(Armagnac is an example)
'member with silver is able to set up' is the wordplay.
'member' becomes 'arm' (arm is a kind of member).
'with' says to put letters next to each other.
'silver' becomes 'ag' (Ag is the chemical symbol for silver).
'is able to' becomes 'can' (I've seen this before).
'set up' says the letters should be written in reverse.
'can' back-to-front is 'nac'.
'arm'+'ag'+'nac'='ARMAGNAC'
(Other definitions for armagnac that I've seen before include "Kind of brandy" , "Liquor" , "Variety of brandy distilled in district of Gascony SW France" , "Type of brandy" , "Spirit" .)
