Is it used to eat Chinese pork? Yes (9)
I believe the answer is:
chopstick
'pork? yes' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'is it used to eat chinese' is the wordplay.
I cannot quite see how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found within the answer.
'chinese' could be 'ch' (abbreviation) and 'ch' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for chopstick that I've seen before include "member of consumer association" , "Oriental eating utensil" , "In the plural, they're oriental cutlery" , "Eastern eating utensil" .)
