Tailback? Blimey! (3)
I believe the answer is:
god
'tailback?' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for god that I've seen before include "Deity" , "Divinity" , "eg Cupid" , "Superhuman being" , "Worshipped figure" .)
