Show first sinner holy books (5)
I believe the answer is:
event
'show first' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'sinner holy books' is the wordplay.
'sinner' becomes 'Eve' (Biblical figure).
'holy books' becomes 'NT' (New Testament).
'eve'+'nt'='EVENT'
Can you help me to learn more?
(Other definitions for event that I've seen before include "case" , "Incident - final outcome" , "heat, perhaps" , "Something taking place" , "What will happen" .)
