Rice that goes 'pop' when you add a quantity of toddy? (5)
I believe the answer is:
paddy
'rice' is the definition.
(I know that paddy is a type of rice)
'goes pop when you add a quantity of toddy?' is the wordplay.
I cannot quite understand how this works, but
'pop' could be 'pa' (both can mean father) and 'pa' is found in the answer.
'quantity' could be 'd' (D is an example) and 'd' is found within the answer.
This explanation may well be incorrect...
'that' is the link.
Can you help me to learn more?
(Other definitions for paddy that I've seen before include "One regularly flooded" , "Wobbly" , "Rice field; fit of temper" , "Field where rice is grown" , "area for rice-growers" .)
