Somewhat heathenish female? (3)
I believe the answer is:
hen
'female?' is the definition.
(female chicken)
'somewhat heathenish' is the wordplay.
'somewhat' indicates a hidden word.
'HEN' is hidden in the letters of 'heathenish'.
(Other definitions for hen that I've seen before include "Insufficient in amount" , "Adult female chicken" , "Domestic egg layer" , "Coop resident" , "Source of eggs" .)
