A bite to drink? (3)
I believe the answer is:
nip
This clue is a triple definition!
'a bite' is the first definition.
(nip is a kind of bite)
'to' is the second definition.
(thesaurus)
'drink?' is the third definition.
(thesaurus)
(Other definitions for nip that I've seen before include "Feeling cold" , "Pinch using pin" , "Light bite" , "Small drink of spirits" , "Small drink or small bite" .)
