Kane sadly died without clothing (5)
I believe the answer is:
naked
'without clothing' is the definition.
I can't tell whether this definition defines the answer.
'kane sadly died' is the wordplay.
'sadly' indicates anagramming the letters.
'died' becomes 'd' (abbreviation next to the year of someone's death).
'kane' is an anagram of 'nake'.
'nake'+'d'='NAKED'
Can you help me to learn more?
(Other definitions for naked that I've seen before include "Blatant" , "Completely unclothed" , "In one's birthday suit" , "Bare" , "In the altogether" .)
