Local drunk has laugh getting drink (7)
I believe the answer is:
alcohol
'drink' is the definition.
(alcohol is a kind of drink)
'local drunk has laugh' is the wordplay.
'drunk' is an anagram indicator.
'has' indicates putting letters inside.
'laugh' becomes 'ho' (representation of a laughing sound).
'local' anagrammed gives 'alcol'.
'alcol' enclosing 'ho' is 'ALCOHOL'.
'getting' is the link.
(Other definitions for alcohol that I've seen before include "Intoxicating liquid" , "Intoxicant in wine, etc." , "Intoxicating liquour" , "The bottle" , "wine, say" .)
