Many come shuffling round for a drink (5)
I believe the answer is:
medoc
'a drink' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'many come shuffling round' is the wordplay.
'many' becomes 'D' (Roman numeral for 500).
'shuffling' is an anagram indicator.
'round' is an insertion indicator.
'come' anagrammed gives 'meoc'.
'd' put inside 'meoc' is 'MEDOC'.
'for' is the link.
Can you help me to learn more?
(Other definitions for medoc that I've seen before include "Wine-growing area" , "Type of wine" , "region of France" , "French intoxicant" , "that's regularly drunk?" .)
