Heir of Isaac Hayes auditioning covers (4)
I believe the answer is:
esau
'heir' is the definition.
Both the definition and answer are singular nouns.
Maybe there's an association between them I don't understand?
'isaac hayes auditioning covers' is the wordplay.
'covers' indicates the answer is hidden within the clue (I've seen 'covered' mean this (the answer is covered up by the clue)).
'ESAU' is hidden within 'isaac hayes auditioning'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for esau that I've seen before include "Twin brother of Jacob" , "Jacob's brother (Gen.)" , "Cheated brother" , "Biblical brother to Jacob" , "Son of Isaac, brother to Jacob (Bible)" .)
