Deaf drunk will turn pale (4)
I believe the answer is:
'turn pale' is the definition.
'deaf drunk' is the wordplay.
'drunk' is an anagram indicator.
'deaf' is an anagram of 'FADE'.
'will' is the link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for fade that I've seen before include "Grow dull" , "Dwindle" , "Lose colour or vitality" , "Gradually grow faint" , "Wither away" .)
