Drink making you sardonic in speech? (3)
I believe the answer is:
rye
'drink' is the definition.
(rye is a kind of drink)
'sardonic in speech?' is the wordplay.
'sardonic' becomes 'wry' (I've seen this before).
'in speech?' indicates a 'sounds like' (homophone) clue (I've seen 'in speech' mean this).
'wry' sounds like 'RYE'.
'making you' acts as a link.
(Other definitions for rye that I've seen before include "Gypsy gentleman" , "Type of whisky" , "Hard liquor" , "Cereal plant; whisky" , "Grass related to wheat" .)
