Female from Passchendaele (3)
I believe the answer is:
hen
'female' is the definition.
(I've seen this before)
'from passchendaele' is the wordplay.
'from' indicates a hidden word.
'HEN' is hidden within 'passchendaele'.
(Other definitions for hen that I've seen before include "Source of eggs" , "Not cock" , "Laying bird" , "Adult female chicken" , "Coop resident" .)
