The booze of Tralee (3)
I believe the answer is:
ale
'the booze' is the definition.
(I've seen this before)
'of tralee' is the wordplay.
'of' indicates a hidden word.
'ALE' is hidden in the letters of 'tralee'.
(Other definitions for ale that I've seen before include "Alcoholic beverage" , "The A in CAMRA" , "English beer in sales" , "brewing?" , "One beer" .)
