Deity makes no uproar (4)
I believe the answer is:
odin
'deity' is the definition.
(Odin is an example)
'no uproar' is the wordplay.
'no' becomes 'O' (resembles 0 - 'no' can mean 'zero').
'uproar' becomes 'din' (both can mean a commotion or fuss).
'o'+'din'='ODIN'
'makes' is the link.
(Other definitions for odin that I've seen before include "King of Norse gods" , "Legendary ruler" , "God - I nod (anag)" , "Mythological Norse god of war" , "Chief Norse god" .)
