Graduate getting prisoner something for breakfast (5)
I believe the answer is:
bacon
'something for breakfast' is the definition.
I can't judge whether this defines the answer.
'graduate getting prisoner' is the wordplay.
'graduate' becomes 'ba' (someone with a Bachelor of Arts degree).
'getting' means one lot of letters go next to another.
'prisoner' becomes 'con' (abbreviation for 'convict').
'ba'+'con'='BACON'
Can you help me to learn more?
(Other definitions for bacon that I've seen before include "Salted pork" , "Salted pig-meat" , "Francis ---, Ir. painter" , "Cured pig-meat" , "Meat - essayist - painter" .)
