Finally stuffed with food? (3)
I believe the answer is:
'food?' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'finally stuffed' is the wordplay.
'FED' is hidden within the letters.
But, I'm uncertain how the hidden word is indicated.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for fed that I've seen before include "Given sustenance" , "US agent" , "Gave food to (someone)" , "supplied with power?" , "Given food to eat" .)
