Canine elevated to become Anubis? (3)
I believe the answer is:
god
'anubis?' is the definition.
(anubis is a kind of god)
'canine elevated' is the wordplay.
'canine' becomes 'dog' (dog is a kind of canine).
'elevated' shows that the letters should be reversed in order (in a down clue, letters go up).
'dog' back-to-front is 'GOD'.
'to become' acts as a link.
(Other definitions for god that I've seen before include "Anubis?" , "Eg, Quetzalcoatl" , "eg Cupid" , "Supreme being" , "Worshipped figure" .)
