Level with Adam’s wife (3)
I believe the answer is:
eve
'adam's wife' is the definition.
(in the Garden of Eden)
'level with' is the wordplay.
'with' indicates the answer is hidden within the clue.
'EVE' is hidden in the letters of 'level'.
(Other definitions for eve that I've seen before include "Female" , "when it gets dark" , "Threshold" , "Later in the day, in short" , "Adam's wife" .)
