Indigenous person in Burma or Indonesia (5)
I believe the answer is:
maori
'indigenous person' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe there's an association between them I don't understand?
'in burma or indonesia' is the wordplay.
'in' indicates the answer is hidden within the clue.
'MAORI' is hidden within 'burma or indonesia'.
Can you help me to learn more?
(Other definitions for maori that I've seen before include "antipodean language" , "native people" , "Indigenous New Zealanders" , "aboriginal inhabitant" , "Native Kiwi" .)
