The King verily sleeps awkwardly (5,7)
I believe the answer is:
elvis presley
'the king' is the definition.
(I have seen 'The King' mean 'elvis presley' so perhaps 'king' could also mean 'elvis presley')
'verily sleeps awkwardly' is the wordplay.
'awkwardly' indicates an anagram.
'verily'+'sleeps'='verilysleeps'
'verilysleeps' is an anagram of 'ELVIS PRESLEY'.
(Other definitions for elvis presley that I've seen before include "The King" , "Popular American singer" .)
