Nourishing sausage ingredient if nothing more (4)
I believe the answer is:
sago
'nourishing sausage ingredient' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'if nothing more' is the wordplay.
'if' becomes 'sag' (I can't explain this - if you can you should give a lot more credence to this answer).
'nothing more' becomes 'O' (resembles 0).
'sag'+'o'='SAGO'
Can you help me to learn more?
(Other definitions for sago that I've seen before include "Palm cereal" , "Starchy cereal used in puddings" , "Edible palm starch" , "Starchy grain used in desserts" , "Powdery starch from a palm" .)
