Alcoholic drink creates trouble, we hear (3)
I believe the answer is:
ale
'alcoholic drink' is the definition.
(I've seen this before)
'trouble we hear' is the wordplay.
'trouble' becomes 'ail' ('ail' can be a synonym of 'trouble').
'we hear' shows a homophone (sound like).
'ail' is a homophone of 'ALE'.
'creates' acts as a link.
(Other definitions for ale that I've seen before include "Sold in 23" , "Alcoholic beverage" , "English beer, may be bitter" , "Beer consumed in sales" , "A drink; sounds like become ill" .)
