At the end of the day, he gives a cry (3)
I believe the answer is:
hey
'gives a cry' is the definition.
I can't tell whether this defines the answer.
'at the end of the day he' is the wordplay.
'at' is a charade indicator (letters next to each other).
'the end of the' indicates one should take the final letters.
The last letter of 'day' is 'y'.
'y' after 'he' is 'HEY'.
Can you help me to learn more?
(Other definitions for hey that I've seen before include "Call attracting attention" , "Exclamation to call attention" , "Exclamation calling attention" .)
