Level with first women (3)
I believe the answer is:
eve
'women' is the definition.
(I know that Eve is a adult female)
'level with' is the wordplay.
'with' indicates the answer is hidden within the clue.
'EVE' can be found hidden inside 'level'.
'first' is the link.
(Other definitions for eve that I've seen before include "Day before; girl's name" , "Mother of Abel" , "Woman of Eden" , "She reportedly lived first" , "Adam's wife" .)
