Doesn't become the worse for drink (6)
I believe the answer is:
stoned
'doesn't become the worse for drink' is the definition.
I can't judge whether this defines the answer.
'doesn't become' is the wordplay.
'become' indicates an anagram.
'doesnt' is an anagram of 'STONED'.
Can you help me to learn more?
(Other definitions for stoned that I've seen before include "Slangily drunk or biblically executed" , "Incapable from drug-taking" , "Slangily drunk in Ostend" , "Like Olive perhaps" , "Are cherries so" .)
