Go red in the face after bishop leaves drunk (4)
I believe the answer is:
lush
'drunk' is the definition.
(lush is a kind of drunk)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for lush that I've seen before include "Fancy" , "Of grass, growing thick and strong" , "Like healthy plants" , "Prolific" , "Succulent - heavy drinker" .)
