Orange tongue (8)
I believe the answer is:
mandarin
This clue is a double definition.
'orange' is the first definition.
(thesaurus)
'tongue' is the second definition.
(Mandarin is an example)
(Other definitions for mandarin that I've seen before include "Reddish-orange, loose-skinned citrus fruit" , "Small orange-like fruit (from China?)" , "Powerful official; fruit" , "Fruity" , "Language formerly used by educated Chinese, or a kind of orange" .)
