When Penny drops off man at home (3,6)
I believe the answer is:
aha moment
'when penny drops off man at home' is the definition.
I can't judge whether this definition defines the answer.
'off man at home' is the wordplay.
'off' indicates anagramming the letters.
'man'+'at'+'home'='manathome'
'manathome' is an anagram of 'AHA MOMENT'.
Can you help me to learn more?
(Other definitions for aha moment that I've seen before include "A crossword might give you one" , "when light dawned" , "epiphany" .)
