Organise sale of drinks (4)
I believe the answer is:
ales
'drinks' is the definition.
(ale is a kind of drink)
'organise sale' is the wordplay.
'organise' indicates an anagram.
'sale' is an anagram of 'ALES'.
'of' acts as a link.
(Other definitions for ales that I've seen before include "Types of beer" , "Alcoholic drinks" , "A sale of beers" , "What might be delivered by pumps" .)
