Prefix with natal or noir (3)
I believe the answer is:
neo
'prefix with natal or noir' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for neo that I've seen before include "Prefix meaning new, maybe one" , "Prefix meaning new or recent" , "New (suffix)" , "language" , "Hero of The Matrix films; new (prefix)" .)
