Something half-heartedly organised for Indonesian (8)
I believe the answer is:
sumatran
'for indonesian' is the definition.
(Sumatran is an example)
'something half-heartedly organised' is the wordplay.
I cannot quite understand how this works, but
'organised' could be 'ran' (run can mean to manage or organise) and 'ran' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for sumatran that I've seen before include "Indonesian islander" , "Indonesian island" , "from a large island" , "type of rhino" .)
