Deity offering bold sign oddly missed (4)
I believe the answer is:
odin
'deity' is the definition.
(I've seen this before)
'bold sign oddly missed' is the wordplay.
'oddly missed' means one should take alternating letters (odd-numbered letters are ignored).
'bold'+'sign'='boldsign'
The alternating letters of 'boldsign' are 'ODIN'.
'offering' acts as a link.
(Other definitions for odin that I've seen before include "Chief Norse god" , "Mythological Norse deity" , "Supreme god of war in Norse mythology" , "Old Scandinavian" , "Legendary ruler" .)
