Regularly envied woman (3)
I believe the answer is:
eve
'woman' is the definition.
(Eve is an example)
'regularly envied' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The alternating letters of 'envied' are 'EVE'.
(Other definitions for eve that I've seen before include "Day before (an event)" , "when it gets dark" , "Adam's wife" , "Period immediately before" , "One from Genesis" .)
