A sweet little boy, I keep mum and dad’s score! (6,6)
I believe the answer is:
danish pastry
'a sweet' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'little boy i keep mum and dad's score' is the wordplay.
'little boy i' becomes 'dani' (I can't explain this - if you can you should give a lot more credence to this answer).
'keep mum' becomes 'sh' (both are ways of telling someone to be quiet).
'and' means one lot of letters go next to another.
'dad's' becomes 'pa's' (pa can mean someone's father).
'score' becomes 'try'.
'dani'+'sh'+'pas'+'try'='DANISH PASTRY'
Can you help me to learn more?
(Other definitions for danish pastry that I've seen before include "something sweet to eat" , "Iced cake" , "Flat cake - and party's his! (anag)" , "Baker's product" , "It goes well with morning coffee" .)
