Possibly breakfast time (8)
I believe the answer is:
porridge
This clue might be a double definition.
'possibly breakfast' is the first definition.
'porridge' can be an answer for 'breakfast' (porridge might be eaten for breakfast). I am unsure of the 'possibly' bit.
'time' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for porridge that I've seen before include "Morning oats" , "Jail sentence" , "Possibly breakfast - time in prison" , "Breakfast dish of boiled oatmeal" , "Or griped about the dish" .)
