Cry during homework (3)
I believe the answer is:
mew
'cry' is the definition.
(mew is a kind of cry)
'during homework' is the wordplay.
'during' indicates a hidden word.
'MEW' is hidden in the letters of 'homework'.
(Other definitions for mew that I've seen before include "Miaow" , "Seagull" , "Cat's sound" , "Feline sound" , "Animal sound" .)
