New omens enthral ladies (5)
I believe the answer is:
women
'ladies' is the definition.
(I know this)
'new omens enthral' is the wordplay.
'enthral' indicates a hidden word (I've seen 'enthrals' mean this (hidden letters are captured or enthralled)).
'WOMEN' can be found hidden inside 'new omens'.
(Other definitions for women that I've seen before include "Adult human females" , "Ladies" , "half of our race" .)
