Dead singer somehow lives (5)
I believe the answer is:
elvis
'dead singer' is the definition.
'elvis' can be an answer for 'singer' (I've seen this before). I'm unsure of the 'dead' bit.
'somehow lives' is the wordplay.
'somehow' indicates an anagram.
'lives' with letters rearranged gives 'ELVIS'.
Can you help me to learn more?
(Other definitions for elvis that I've seen before include "Stop!" , "US singer; lives (anag.)" , "Legendary singer" , "Much-impersonated singer, d. 1977" , "Lives for rock'n'roll king" .)
