Orange Chinese of high rank (8)
I believe the answer is:
mandarin
This clue might be a double definition.
'orange' is the first definition.
(I've seen this in another clue)
'chinese of high rank' is the second definition.
'mandarin' can be an answer for 'chinese' (Mandarin is an example). I am not certain of the 'of high rank' bit.
Can you help me to learn more?
(Other definitions for mandarin that I've seen before include "Tongue" , "Top civil servant" , "Small orange-like fruit (from China?)" , "High-ranking bureaucrat" , "Drain man (anag) - high-ranking Chinese official" .)
