Maybe he lives! (5)
I believe the answer is:
elvis
'maybe he' is the definition.
The definition suggests a singular noun which matches the answer.
'lives' is the wordplay.
'lives' can be anagrammed to 'ELVIS'.
However, I am not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for elvis that I've seen before include "Legendary singer" , "Stop!" , "Singers Presley or Costello" , "Mister Presley for one" , "Singer Presley" .)
