Cambodian (5)
I believe the answer is:
khmer
'cambodian' is the definition.
(I know that cambodian can be written as Khmer)
This is the entire clue.
(Other definitions for khmer that I've seen before include "Native Cambodian" , "Language of Cambodia" , "'... Rouge, led by Pol Pot in Cambodia (5)'" , "Cambodian language" , "Asian" .)
