Drunkard takes Coke product half-heartedly (3)
I believe the answer is:
sot
'drunkard' is the definition.
(sot can mean a drunken person)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for sot that I've seen before include "Lush" , "Boozer" , "Habitual drinker" , "Toper" , "One's often intoxicated" .)
