Native of Borneo weaving a Tongan rug, shortly (9)

I believe the answer is:

orangutan

I'm a little stuck... Click here to teach me more about this clue!

'native of borneo' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.

'weaving a tongan rug shortly' is the wordplay.
'weaving' indicates an anagram.
'shortly' means to remove the last letter.
'a'+'tongan'+'rug'='atonganrug'
'atonganrug' with its last letter removed is 'atonganru'.
'atonganru' with letters rearranged gives 'ORANGUTAN'.

Can you help me to learn more?

(Other definitions for orangutan that I've seen before include "a big sub-human creature" , "Primate" , "ape" .)

I've seen this clue in The Times.
