Collection of myths, each with divine content (4)
I believe the answer is:
edda
'collection of myths' is the definition.
(I've seen this before)
'each with divine content' is the wordplay.
'each' becomes 'ea' (abbreviation).
'with' is an insertion indicator.
'divine content' becomes 'dd' (DD is an example. I am not sure about the 'divine' bit.).
'ea' placed around 'dd' is 'EDDA'.
Can you help me to learn more?
(Other definitions for edda that I've seen before include "mythic florilegia" , "Collection of Norse poems" , "of Old Norse poems" , "Collection of old songs" , "Collection of myths" .)
