She may be broody during the night (3)
I believe the answer is:
hen
'she may be broody' is the definition.
I can't tell whether this definition defines the answer.
'during the night' is the wordplay.
'during' indicates the answer is hidden within the clue.
'HEN' is hidden within 'the night'.
Can you help me to learn more?
(Other definitions for hen that I've seen before include "Female lobster, fowl" , "Farm bird" , "Composed of women" , "Insufficient in amount" , "Coop resident" .)
