Furious policeman receiving nothing in support — one's a source of repeated documents (11)
I believe the answer is:
photocopier
'source of repeated documents' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'furious policeman receiving nothing in support one's a' is the wordplay.
I cannot really understand how this works, but
'policeman' could be 'cop' (slang term) and 'cop' is located in the answer.
'nothing' could be 'o' (O resembles 0) and 'o' is present in the answer.
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for photocopier that I've seen before include "image-maker!" , "Occur" , "Office machine" , "Reproductive device" .)
