Very new child (3)
I believe the answer is:
son
'child' is the definition.
(male child)
'very new' is the wordplay.
'very' becomes 'so' (both can mean 'extremely').
'new' becomes 'n' (abbreviation as in New Testament NT).
'so'+'n'='SON'
(Other definitions for son that I've seen before include "Male offspring" , "A relative" , "Express paper" , "Native" , "Male child" .)
