Shades among sugar crop from Chinese region (9)
I believe the answer is:
cantonese
'chinese region' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'shades among sugar crop' is the wordplay.
'shades' becomes 'tones' ('tone' can be a synonym of 'shade').
'among' indicates putting letters inside (inserted letters are placed among others).
'sugar crop' becomes 'cane' (I've seen this in another clue).
'tones' put into 'cane' is 'CANTONESE'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for cantonese that I've seen before include "such food?" , "tongue" , "Chinese language" , "Asian language?" , "Form of Chinese" .)
