Stick to whiskey, also (4)
I believe the answer is:
wand
'stick' is the definition.
(thesaurus)
'whiskey also' is the wordplay.
'whiskey' becomes 'w' (alpha bravo charlie delta ...).
'also' becomes 'and' (I've seen this before).
'w'+'and'='WAND'
'to' acts as a link.
(Other definitions for wand that I've seen before include "Conjuror's stick" , "Magician's prop" , "Magic rod?" , "Rod of magician or water-diviner" , "Fairy's stick" .)
