Drunk is yet to swallow medium Scotch (6)
I believe the answer is:
stymie
'scotch' is the definition.
The definition and answer can be both to do with social activities as well as being verbs in their base form.
Maybe there's a link between them I don't understand?
'drunk is yet to swallow medium' is the wordplay.
'drunk' indicates anagramming the letters.
'to swallow' indicates putting letters inside.
'medium' becomes 'm' (as in UK clothing sizes).
'is'+'yet'='isyet'
'isyet' anagrammed gives 'styie'.
'styie' going around 'm' is 'STYMIE'.
Can you help me to learn more?
(Other definitions for stymie that I've seen before include "Block or obstruct as in golf (6)" , "'Hinder, prevent progress (6)'" , "Obstruction (originally at golf)" , "Thwart -- my ties (anag)" , "Thwart (as once was possible on the green)" .)
