Source of some Australian’s annoyed comment about West Indies (6)
I believe the answer is:
darwin
'source of some australian's' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'annoyed comment about west indies' is the wordplay.
'annoyed comment' becomes 'darn' (I can't justify this - if you can you should give a lot more credence to this answer).
'about' is an insertion indicator.
'west indies' becomes 'wi'.
'darn' enclosing 'wi' is 'DARWIN'.
Can you help me to learn more?
(Other definitions for darwin that I've seen before include "Charles . . . . . ., great scientist of evolution" , "Evolution pioneer" , "Turn inward for the antipodean city" , "Originator of the theory of evolution" , "Charles ... who put forward theory of evolution" .)
